Get to know the counter guys at a local plumbing supply, it may be a little more expensive in the beginning, but once you get to know them you'll get better pricing and they're always good about answering questions and explaining things. They'll also let you borrow tools without charge once they know you and, if you do need a plumber for something, they can recommend a good one. Soldering is easy just make sure everything is clean and fluxed. Personally, I would use Pro Press, they're even easier and faster.
