Nice system! Congrats on all the new gear.
For speaker wire, you don't need to go expensive. I like the site linked
here for a good recommendation of the gauge to get for your speakers and the distances of wire that you'll be using. Monoprice.com is a good place to get inexpensive quality wires. However, you might want something sooner than they could deliver (since you're setting up this weekend), so let us know if you want recommendations for local stores. There are many places to get cable, and typically you'd pay more for aesthetics.
For surge protection, there are several threads on the forum for that. I have a Belkin PureAV console (and bought my parents a Belkin power strip) and am happy with it. I have an APC power strip on my computer system.
