I'm looking to try to find someone that has bought a AC charging Kit to check my van with it is it possiable to check it with just the gauge that comes with the kit or do I need to have a can of stuff on the gauge too?

The gauge by itself is fine, just make sure the can tapper side is closed.
After a minimum charge is achieved, start the compressor and set system to medium fan. When the compressor cycles on and off about every 45 to 60 seconds stop the flow of refrigerant. Check the vent for cooling. If cooling is inadequate or compressor is cycling excessively add small amounts of DURACOOL 12aŽ by opening and closing valve handle. Low side pressures should read between 28 and 45 psi.
If you lost a/c oil and that's causing your compressor to be loud, you should take it to a shop.
The best thing to do would be to find the source of the leak, fix it, and then refill.
