Critique my build

[der_kluge]

It's an Assassin/Tempest/Fighter build.

Looking for constructive criticism.

I'm shooting for a character than can DPS with lots of backstab, be highly effective at ranged combat, and who can also pick all the traps/doors in the game. Since, let's face it, people see a rogue, they expect them to do all the traps, etc.

The extra fighter levels are for bonus feats.

Specific questions I have:
Does alignment really matter?
Should I bother trying to keep hide/move silently high? Or are they really only useful in solo play? Are they like Jump - and their effectiveness sort of dwindles over time?
Do I need more than 1 rank in Tumble? I put ranks in there early on, but it sort of went by the wayside later on.
Any reason to dump points in Swim? Do I have too many in jump? Would it make sense to even these out?

Thanks for looking.

This is all without any gear. At a minimum, I'd put +6 dex, +6 con, +6 wis on this guy, with +15 Search/Spot goggles, and probably DD/OL gloves. I don't have access to lots of rare named stuff or green steel things, so it would just be basic stuff.
