seeking advice for a Crossbow Rogue

[BLugas]

^Yeah...
Since the lag this weekend made the game unplayable, I decided to have some fun with the Build Planner, and i ended up making an interesting, yet unrevised, 18 Rogue/2 Fighter build, which is crossbow based.
Take a look:

and before anyone calls me a noob;Yes, I am fully aware that to Sneak Attack with ranged weapons you have to be 10 meters or less from your target.
One interesting thing that I found out is that Attributes & Skill enhancements from class and from race actually stack, which is very interesting.
and Yes, I know I spent too much points on intelligence and in some useless skills/one point wonders (Haggle and Tumble);and that I have no Mêlée feats...

Too bad that Kobolds are not a Playable Species...

Any comments?
