The camera won't take better pictures, only you can do that.
The mechanics of a film camera are just like digital when it comes to exposure, so you'll want to understand the exposure triangle and how ISO, shutter speed and aperture work. Also, the big thing with film is that you have to choose the ISO when you buy the film and are stuck with it for the duration of that roll. This is where a lot of people go wrong, and why a lot first rolls are either mostly clear or mostly black when processed.
If the SLR has auto exposure modes they should be very similar to current DSLR's.
Bracketing.. this is where you shoot an exposure under what you think it should be, one where you think it should be, and one over where you think it should be. And it's why film shooters often only get 12 individual images on a 36 exposure roll. If you're learning to use a film SLR then you probably want to bracket.
Another thing to note.. it's difficult to find 35mm film over ISO 1600 in many stores (you need a camera shop). a lot of people find this limiting since many digital cameras go past ISO 1600 now. And the cheaper films at those speeds have big honking grains that make digital noise look like nothing. So it's something to keep in mind if you plan to do any low light work.
I love film and still use it often. I find it very rewarding because it does take a little more know how overall than shooting digital.
