[V8] cold start, idle speed, hydraulic fluid and speaker questions

[z1sales at z1auto.com]

Well, we are finally almost done with the V8 and just have a few more items to take care of before
she is perfect (well, for a 15 year old car!).  Title will finally be in my hands tomorrow, so this
maybe the week where she makes her maiden voyage in who-knows-how-many-years.

1. cold start/cold idle - when we start the car after it has sat overnight for example, it will
idle, though if you give it any gas while in reverse or drive, it will go, and then stall. 
Restarts right away.  Once the car has warmed up a bit, it's fine.  Anything that jumps off the
page as being the "goto part" to check/clean/replace?  Also, what is the idle speed supposed to be
when the car is cold vs when its warmed?   It's had a tune up done since I got it (new caps,
rotors, plugs, wires looked ok so left them)

2. hydraulic fluid - I have a case of the Pentosin 11s at the shop, so since every other fluid in
the car has now been swapped for fresh stuff, figured mind as well tackle the hydraulic fluid too. 
Is there a write up as to the proper way to flush/fill?  

3. My car has an aftermarket headunit and the stock Bose speakers...only the passenger side Bose
works, and from all i have read, it's just as well!  Is there anything special required to replace
the front and rear door/deck speakers?  I'm not going for high end sound at all....more along the
lines of (fingers crossed) dropping it off at Ciruit City for an afternoon and having them swapped?
 Anything special I should know?

4. Anyone have a spare center cap they want to get rid of (non BBS)

thanks guys...appreciate the assistance as usual!
