Since I am new to this, I do not know the details. How much voltage to apply for a certain amount of time for a measured thickness of deposit on the cathode, or what would be the best salt solution of a particular metal to use? Or would applying heat to the electrolyte solution help or hurt the process?

The current is more important than the voltage for this, and while I'm sure you can convert that voltage into current via the equation V = IR, I'm not too sure at the moment.

Anyway, if we take silver for example:

Ag+ + e- → Ag

So basically the rate at which I deposit Silver depends on how fast this reaction happens, i.e. how much current is driven through the system. To work out how big a current I need given the amount of time I have, I need to know the following:

1. Density of Silver (ρ, 10.5 g cm

^{-3})

2. Surface Area to be plated (A)

3. A

_{r} of Silver (107.9 g mol

^{-1})

So we could do this the long way...

Q = It (Charge = Current x Time)

N = Q/e = It/e (Number of Electrons or Silver Atoms formed = Charge / Elementary Charge)

N = Aρ/A

_{r} (Number of Silver Atoms Required per cm = Surface Area x Density of Silver

So per cm of thickness, I need to deliver:

It/e = Aρ

I = (Aρe/A

_{r}t) Amperes of Current.

The short way would involve using Faraday's Constant, 96500 Coulombs per Mole. The maths is similar.
