Replying to Question about Film Photography

I have a quick question about film. First off i bought a minolta x-370 and had it for a day and somehow the shutter got stuck, i understand this is common for minolta x series cameras. Anyone have this problem before?

Next i have a question about light metering. Ive always wondered how to know what your photo will look like on film (overexposed/underexposed) since unlike my t2i there isnt a preview live mode thing. Then i heard about light meters and have never really understood it. I youtubed it and i still havent wrapped my head around it. Does it show you what your photo will look like according to your apeture/shutter speed/iso? Any insight will be extremely helpful.

Lastly im wondering which is a better camera to be shooting film on. Canon tlb or AE-1?

Sorry for the noobness.
