I'm thinking of making a marksman focusing on the sniper path of the marksman. Maybe taking a couple levels of Soul Bolt to make the crossbow and have the feat that lets my total level count as soulbolt level for purposes of enhancement bonus. Also grabbing the feat that lets me refocus for a move action.
Then grabbing boots of Skate and having at it. Any advice? Feat lines to stay away from?

I'm not an expert on the Sniper Marksman, never played it. But I know they focus on a single shot. The fact that their scaling damage dice stacks with the Vital Strike feat chain has always amused me greatly. You could always move to a good sniper position, then use the level 8 Sniper ability + Vital Strike to snipe at someone. Once you're in a good position, move action to regain focus, and expend it for another sniper shot. Again, there are probably better build options, but its a fairly simple, workable build.

Any particular reason for crossbow instead of comp. long bow?
This would allow you to just focus on DEX(AC & hit) and WIS (damage on all attacks with the mindbolt and PP/powers), as well as ignore STR.
1 Soulbolt: Weapon Focus- Mindbolt[b], Extra Blade Skill (Focused Offense)[1st]
2 Marksman: Point Blank Shot[b]
3 Soulbolt: Emulate Ranged Weapon-Comp Long Bow [blade skill], Precise Shot[3rd]
4 Soulbolt: Enhancement +1, Psychic Strike +1d8
5 Marksman: Sniper Style etc, Favored weapon CLBow, (Your Enhancement feat)[5th]
6 Marksman: Style Mantra etc,
7 Marksman: Style ability stc, Clustered Strike[7th]

If you use a minotaur double crossbow, your maximized (ideally mythic but let's not be too optimistic here) vital strikes with boosted damage shots can actually approach a longbowman's full attack sequence, which is actually rather spectacular for a weapon that isn't the longbow, although you're building heavily just to keep up.
Make sure the weapon's built of deep crystal. It's cheap, resilient, and bonus damage is bonus damage. Collision enhancement is static damage, and therefore multiplied on crits.
Consider Psycrystal scouts and Deep Focus (get your 2nd focus this way even with a crystal). Since you're not using an x4 firearm, I won't recommend Adaptive Warrior at all. If you were, well, there's a reason you want to get that thing to 6th level when using guns.
If you don't mind multiclassing a little, 4-6 levels of Aegis will compensate your sniper losses with up to two size upgrades for your weapon, which means more base damage. That it just HAPPENS to also allow full flight (and/or burrowing available at moment's notice with reconfiguration: hard to get more hidden in the ground or the side of a cliff than by bloody burrowing), underwater breathing, extended protection versus fatigue/exhaustion/hunger/environmental issues, Evasion in skin form, a speed boost and a free Shield hardpoint + Reloading hand, as well as the legendary moneymaker: Astral Repair.
Huge Crossbow and Shield. Because the guy sniping from 500 feet in the air should actually be a threat!
