Does anyone know what the part missing is or for? I found this picture of what it was but not sure where to get it since SRAMs webpage doesn't really have a parts list for it.

I believe you need part 11.4015.544.090 Compression Damper, Motion Control DNA, Crown Adjust - 2012 Revelation RL (includes compression knob). It is number 19 on the Reba 2009-2011 chart. If that's the case, looks like it's just a screw. I'm not 100% on that though. I have FOX on my bikes. I would send the pic to SRAM customer service and they could tell you for sure.
Another question I have is about my disc breaks. There are Avid Juicy 3 brakes on my bike and when I first got it they squealed and then after riding the noise went away sometimes and lately the front has been screaming while the rear is relatively quiet. Is this just a common problem with these? I'm assuming if I went to some better breaks besides these entry level the noise would go away?
Even the most expensive brakes could have squealing issues from time to time. This is caused by brake contamination when you have foreign particles on the brakes rotor and brake pads. Put some rubbing alcohol on a clean rag and wipe down your rotors and pads. If they are still making noise take some fine sand paper and lightly sand the brake pads. Clean with rubbing alcohol once again after sanding. If it's still squealing, buy new brake pads and make sure to break them in. Breaking in the brake pads just means going for a ride or two without a lot of hills and lightly breaking often during the ride. Hard breaking on new pads could cause them to gloss over and not be nearly as effective.
Hope that helps.
