I am doing similar setup, I just bought a muffler and I'm going to have a shop custom make me the (b=pipe?) that goes from the cat to the muffler. Do you guys think I should get rid of the resonator? Would it be too loud? I don't want my car to be obnoxiously loud, but I do want my car to have a low growl cruising...and to have a loud growl at WOT.

That Oem muffler can't be beat! The Cattman exhaust system isn't that loud! If you want to quiet things down. I found a resonator called "whisper resonator" from ZZ Performance in which our rival GM boys use to quiet thier sickly loud pushrod V6's! It's 2.5" in/out and 3" in/out, 28" overall lenght, 24" muffler body lenght, 6" round muffler body case! Cost $149.99 for some good ole T-304 SS!
Since the stock muffler flows pretty damn good, mufflers are not a performance mod on a Maxima, they are for looks and sound only.
Sooo, as I said before, you can't beat the stock muffler.

but for my application (supercharged) i believe that its restricting airflow.
i have headers, ypipe, 2.5" piping all the way back, and then the stock muffler, which i believe is like 2" inlet.
im still looking for a stock 2.5" inlet muffler...

i dont even know how to answer this 
when a car is supercharged, the stock exhaust becomes restrictive, thats why it is recommended to upgrade to 2.5" or even 3" piping, to let the engine breath better.
I have a 2.5" piping from the cat-back but using the stock muffler, and the stock muffler is only 2" inlet diameter so it obviously doesnt flow as well as 2.5".
when i had my magnaflow streight through 2.5" muffler, it was loud as hell but i felt that it was making more power. I am not going to go and dyno my car every time i change out a muffler.
if you need more proof just ask this question in the supercharged/turbo section.

AFAIK, stock is a 2.25", the extra .25" is not going to make a huge difference on a S/C motor.
Don't you only have a Y-pipe on the front?
Get some headers before you worry about a muffler that is going to make almost zero difference other than sound.
