Can you guys help me out a bit on bringing back my RC10 to life?

The servo and receiver I will just remove from my Nitro HPI RS4, since I will be using the same transmitter. If I remember, the Orange Team Novak (Speed Control?) and the motor still works.
I did buy a 6cell nimh battery. Is it safe to jump from the nicd 1400 battery to the new one? Bought in on sale for $20 at my LHS.

What I think I need changed is shocks, turnbuckles, and rear wheels. Is there anything u guys see or should upgrade? Where can I buy these parts?
Here are the pics:






Thanks!!!
