Zee, have you ever wet shaved before? If not, you might try a week or so of daily shaving with a bic or similar disposable razor while focusing on prep. Make sure you're getting your whiskers nice and soft before you shave. I recommend that you shave without any prep at all, then shave with a lot of prep, and notice the difference. (With a cartridge razor. Don't try it with your straight.) It'll help you know how to ensure a nice soft beard.
Once you know you have good prep, try shaving the under part of your forearm or the backs of your hands to at least get a start on technique.
I know some of the old-timers here will disagree with me on both of these recommendations, but they come from my own personal life experiences. I've owned and sharpened knives since I was 10, and I've always tested the sharpness by shaving my arm-hairs, so I alreay had a good idea of the best angles to hold the blade. Also, I wet shaved for years with cartridge razors, and I would run the entire range of prep from literally stepping out of the shower and running the razor over my face (no soap, cream, etc.) to hardcore, intensive hot towel and soap lather prep. I honestly believe that those two things gave me a good foundation of experience to be able to pick up a SR and get good results right away.
Oh, and one other thing: buy a brush and lather. There's no right kind of lather, just use whatever shaving soap or shaving cream you want/like. The point is at least use some sort of hot lather. It'll save your face.
