I have a 2002 3.8 n/a. Can the idle speed be adjusted and if so how? Also, what rpm's is the engine supposed to idle at.

It can be adjusted, by tuning the ECU. There is no way to do it otherwise, nor do you need to unless you have a crazy cam setup.
My rpms fully hot in park are right around 850. If your's is low or high then it may be time to clean the TB, MAF and IAC. Then check for vacuum leaks.

command at start up is around 1050
Fully hot idle is 750ish and in gear around 650-700.

idle can be adjusted manually. There is a set screw on the TB 97-03. However if you mess with this..it'll toss a code. Best way is in the PCM

the screw on the TB is just a blade stop. the computer will just adjust the IAC to compensate for what ever you did the the set screw until the diff is too much.. then it will set the SES.
like said you need a tuner to adjust the idle. so DHP or HPtuners.
OP is there a reason you want or need to adjust the idle? maybe we can figure out another solution or help fix what is wrong.
