Most of my cuts are from Expert at the Card Table, I don't remember the names of all of them. As for shuffling, if I'm at a table I usually use the Pull Through shuffle, it's simple, and from my own experiences it's been very effective. I'm also working on the Zarrow Shuffle, and from what I've heard, it's one of the best, despite being a bit knacky. And if I don't have a table, I use a shuffle that I think is by Daniel Madison, which is pretty slick if performed well. It's a bit sloppy, and looks fair and natural and involves the packets "interweaving" side to side rather than end to end.
In my opinion, if you can master a good tabled riffle shuffle and an in-the-hands riffle shuffle, you should have no need for a false overhand or hindu shuffle.
I also thought I'd mention the Truffle Shuffle from Art of Magic. I haven't purchased it yet myself, but I've heard good things about it and the trailer looks very convincing. I'm planning to pick it up soon, so I'll let you know what I think about it then.
As for seconds/centers/bottoms, I almost exclusively use bottoms. Center deals are usually only to impress other magicians, and don't have much applications in performing for laymen, just learn a good bottom control and you're set. Seconds could be useful if you plan on working with a marked deck, but I've found there's not much you can accomplish with a marked deck that you can't with sleight of hand.
Hope this helps.
