With rapid reload and alchemical cartridges, you can get as many shots as you have attacks in a round with pistols. Currently, there is no way to get more than one attack per round with a musket.
After level 5, you add your mDex to damage. Rapid shot for the pistols and deadly aim for damage, magic weapons for damage.
Multiclass after you get the deed that gives you a full attack with a single shot. I forget what its called and I don't want to look it up but you know what I'm talking about if you're a gunslinger.
Pistols if you'd like to twf, but you need weapon cords to do it.
Don't kill your character but crit your enemies and blow their heads off.
But how do i know how many attacks i have in in a round?
If you don't have any feats that let you get more (like Two Weapon Fighting), then you get them according to your Base Attack Bonus. When you get a Base Attack Bonus of 6, you'll have two attacks. 3 attacks for BAB of 11, and 4 for a BAB of 16.
-I get shot of per round, can i in any way get more?....
Sure, the simplest solution is to get a pepperbox, which you can have preloaded giving you up to six attacks before reloading becomes, an issue. I’d also use alchemical cartridges, get the feat rapid reload, or both. You can find the feat in the core rulebook; it normally works with crossbows but works with firearms as well. At 11th level you get deed lightning reload, which combined with either of the above lets you load your firearm once a round as a free action and can be use to extend the “life” of your pepper box as you can then reload a chamber each round for free providing you either use alchemical cartridges or have rapid reload.
At 7th level you get dead shot, which helps here a lot. You can effectively pool all of your damage into a single attack. It’s not quite as effective as using your full attack because bonus damage is only added once but it’s good for when you’ve used up all your preloaded shots.
-Is there any good way to go from here to get higher damage?...feats etc...
Well at 5th level gun training lets you get to add your dexterity bonus to damage, also get the feats point blank shot and deadly aim, both found in the core rulebook. Normally, deadly aim doesn’t work with touch attacks but firearms are an exception making it a must have imho.
-Should I go multiclass?....and what, why and how?...
Depends on your character concept. You can if you want but I don’t think you need to. That said a level of rogue might be nice for the sneak attack damage when flanking if you feel you need it.
-What weapons should I use?....We have only early firearms in our campaign, no advanced....what should I go for?...
I’d probably go for a pair of pepperboxes. Fire until it’s out and then switch. As I mentioned above once you get lightning reload mentioned above you can potentially reload one of the used chambers each round for free letting you get your full attack longer before you need to stop and switch guns or need to start using move actions to reload (at which point you should start using dead shot as mentioned above).
-Should i kill my character, and create a new one?...
Completely your call, if you aren’t having fun with him then yes, of course. But if you’re worried about being effective I would be patient and try it out for a while. The gunslinger isn’t a DPR machine but they can deal out decent damage and do it consistently. Getting to use touch attack AC at short-range means at medium to high levels you’d rarely ever miss. If you find only getting this with the 1st range increment to limiting consider getting the signature deed feat at 11th level and using it with deadeye effectively doubling your touch attack range.
I could have sworn there was a guide to the gunslinger out there somewhere but I’m failing to find it, perhaps someone else will chime in.

Well I was ninja'd on several, ok most points, but what can I say it was a long post x.x
Nope. With just that, you'd have one shot only. Rapid Shot will make it two. At level 6, you'll get another attack as well, from your BAB (as I mentioned before).
Just because you can reload fast enough doesn't mean you can fire that fast.
No, all characters, no matter what class they are, are limited on the number of attacks they get with a full attack action. This limit uses a characters base attack bonus (abbreviated BAB). Normally, someone such as a gunslinger that uses a high BAB gets 1 attack at 1st level, 2 at 6th level, 3 at 11th level, 4 at 16th level, and finally 5 at 20th level. (Incidentally this is the best BAB a character can have)
To modify this number you either need to get a feat if one exists (depends of what you are doing), use both hands (which gives penalties to attack rolls), or have magic used on you such as the 3rd level spell haste.
Projectile weapons that have reload times such as crossbows and firearms may eat into this slowing the rate at which you can attack. While firearms may slow you attack speed they let you use touch attack AC while within 1 range increment (about 20 feet). Because of this you rarely miss within this range which can be nice.
Consequently, to do as much damage as possible you want to reduce the reload times on your firearms so you can shoot more and reload less. A pepperbox is a 6 cylinder/barrel pistol and you can have all 6 preloaded thus you don't need to reload until you run out of ammunition. But as mentioned, this will not increase the number of attacks you can make per round merely avoid reloading for a while so you can get the full number of attacks normally allowed.
Currently, there is no way to get more than one attack per round with a musket.
It's only tangential to this conversation, but this isn't correct.
At third level the Musket Master archetype allows you to reload a musket at the same speed as a pistol as long as you have one grit left.
Anyway... good info otherwise, but thought I would throw this out there.
