Newbie system build questions

[RoamDog]

First of what will probably be several newbie posts...
Building my first system. Using a LanParty UT nF4 Ultra-D.
The backplate has several tiny little prong-like thingies. Almost all of these seem to serve no purpose. Do I just bend them off and remove?
The manual for the mobo is... sparse (at least for a first timer).
I am not sure what to do with all these jumper settings...
There is a jumper for PS/2 Power Select. I can either select 5V or 5VSB. Which should I use and why?
Same question for the jumper controlling USB Power.
I am guessing the Speaker On/Off jumper stays at the Off setting (assuming this is a cheap internal speaker of some sort and not the control for the Karajan Audio Module jacks)?
The S/PDIF jumper has settings for Out via ALC850 and Out via nForce4. Which do I want?

Uh.. sorry dude, I thought I could help but I havent yet set up an nForce4 board. As far as the little prongy things, dont break them off they act like springs and hold tension on the backplate insert to hold is fast. You may want to post some system specs (processor, ram, power supply etc) to help others help you. Someone is gonna ask so you may as well get them up there.

Good luck
