You have great spells. Craft Wondrous Item is one of the best feats. I would take it if the GM allows it and you have the time to craft. You can not go wrong with that feat.
As for your Wand arcane bond. Have you decided what spell you want to put into it and make a wand of? Magic Missile and Scorching Ray are really good for the Levels you are at. If you are looking to save gold I recommend the Magic Missile @ 7th level since it should be cheaper than scorching ray (CL 7) for your caster level. Also, it is 100% accurate where you have to hit with scorching ray. Wand usually is the worst Arcane bond but since you took it you might as well use it. You get the feat to upgrade it for free already.
Your spell list looks good. What are you doing with Magical Lineage Haste? Is this for Quicken spell later?
I would also work on scribing a few scrolls as well if I was you. See invisibility is always great to have a scroll and on hand. So is Mount (I abuse this spell, it has too many uses), Tongues or Clairaudience would be another good one for a scroll so you can prepare the other.
Swapping out the bonded wand for a ring or amulet would definitely be preferable. The problem with bonded wands (and weapons, for that matter) is that you must succeed on a difficult concentration check in order to cast spells when your arcane bond isn't equipped, which means you basically need to hold your wand in your hand to cast spells. This gives you a very serious vulnerability to being disarmed, but also means that for spells involving somatic components (which is virtually all of them) you need to devote both hands to casting spells: one to hold your wand, one to cast the spell. This prevents you from holding or using any other item while casting spells, which is a very annoying problem to have. The benefits of a bonded wand just aren't good enough to justify living with that liability.
It seems very odd that you're 6th level and haven't encountered magical items yet. Even in a low-magic game you'd expect everyone to have around 8,000 gp in magical gear by this point. If your GM is being that stingy with magic, I'm surprised he allowed a Wizard. Crafting is definitely worth your time if magical items are not otherwise available, as the lack of them is going to have a severe impact on the power of the rest of your party.
