I have finally pieced together all the brackets for my JRSC and i am planning on starting the install today. the only thing that i am missing from the kit is the hardware.. am i going to run into an issue of not having bots, nuts, vacuum hoses.. ect.. when i start installing it?

First thing first, I don't know too much on these cars yet.
Second, I'm speaking from my car, svt with jrsc.
Looking at the last pic, my pulleys before and after the s/c are the same size. Pic shows two dif sized pulleys. Idk if this helps....

That's definitely an M45 supercharger which is for the standard zetec, the m62 is for the svt its bigger and won't line up with your manifold. Are you hearing the belt slip mine would squeal for a second when it would slip, and you could actually see my boost drop when it would start slipping.
Here are my pulley sizes (these are measured to outside of the shoulders and are close measurements not exact, inside diam. will be smaller).
SC snout pulley (yours) 3"
Belt idler pulley 2 11/16" right side of sc (facing the sc snout from passenger side of the car)
Power steering pulley 5"
AC pulley 5 3/4"
Crankshaft pulley 5 1/8"
Water pump pulley 4"
Belt tensioner pulley 2 3/4"
Idler pulley 2" left side of the sc (facing the sc snout from the passenger side of the car)
Alternator/generator pulley 2"
SC snout pulley (yours) 3"
Belt idler pulley 2 11/16" right side of sc (facing the sc snout from passenger side of the car)
Power steering pulley 5"
AC pulley 5 3/4"
Crankshaft pulley 5 1/8"
Water pump pulley 4"
Belt tensioner pulley 2 3/4"

Alternator/generator pulley 2"

IMHO your supercharger is been under driven, that's why you are only making 3 psi, I also think your idler pulley is bigger ( not the one from the jrsc kit but the one from the car) therefore your issues with the belt size and also with the jrsc been under driven, the longer the belt the least rpm your accessories get
Belt length doesn't determine how fast a given pulley spins.
Having a larger Idler pulley would simply mean that that Idler would see less RPM's. It could explain the belt length issue though. I know I had to reef on my tensioner pretty good to get enough space to fit my belt on.
The formula for how fast a given pulley spins is:
Crank pulley Diameter/ diameter of pulley your calculating RPM for= Pulley ratio (for each rotation of the crank, this pulley rotates x times)
Pulley ratio* engine RPM = pulley RPM
So the only way the blower would be under-driven is if he has a smaller then stock crank pulley or a larger blower pulley.

Just a shot in the dark, but are you running stock cams? if not, what is your overlap?
If you are absoulutely certain that you have no vacuum leaks, I would change your pulleys to the large crank, smaller S/C ones, if you do not see significant improvement in boost, your s/c is not producing boost. Any chance someone did a home port job on it?
just thinking out loud, we kinda.

ps: I will have an m45 s/c for sale soon if yours turns out to be bad.

You may have a vacuum/pressure leak which is not showing up until you are under boost.
I had the same conditon when I did my set-up I ended up using a manifold/head gasket from retroford and trimming it for the fuel injectors. Moss does not sell the intake/head gasket.
