NAD 3140 - I know nothing

I have just bought this NAD 3140 integrated amp and know nothing about it at all. In fact, I know nothing about hi fi at all, but I love well-reproduced music (jazz, classical, really old blues and other American "roots" music, and lots more besides), so I want to start learning. Unfortunately, my budget is extremely meagre.

I've searched around on the 'net and found references to a legendary NAD 3020 and a few others. They all seem to be well thought of, but nothing about this one, even specifications - and I don't even know how many watts output it has!

What I'd be most gratful for would be recomendations for cheap old speakers to match it, and a tuner too. Because I've read that CD players are more likely to be faulty, I've been thinking of using a new DVD player with it to play CDs (and kill two birds with one stone - I'll be able to watch DVDs too) - is that a good idea?

Just can't seem to get this kind of advice down here in New Zealand!
