Whatever method will work for you, for the most part the spreading should come from the fingers when most people do, again there's no real method. Even though people learn a set technique for table spreads, ie these fingers here, here, and here. Once you master the basics of the table spread you can pretty much do the spread any way you want cause you know how the deck behaves to beveling and so forth.
As for catches, what particular catch are you trying to learn right now? There are no turnover down catches, half-turnover down catches, and same hand fall catches. I'll assume that it's the same hand fall catch because that's one people seem to want to learn first.
You shouldn't really be putting too much force into the "tossing" of the spread. Think of lift your arm and then dropping suddenly to catch the spread. The spread holds the shape easier than actually tossing with force. Follow the tips I gave above, if the spread isn't good to begin with, it's not going to be good for anything. In that case, in performance situations, do a glide catch or down catch, if you realize the spread isn't good. A good practice method to help you keep from dropping so much is to practice over your bed. No bad bed jokes here, but the bed isn't as high as a table, but definitely not as low as the floor. Plus the sheets(which should be clean) will help you deal less with deck condition.
