There are a number of great options: I suggest the Shunyata Venom 3 power cord because it costs $99 and nothing touches it for less than $200, IMHO. I added one to my father's NAD and, while he's no audiophile, he loved the result.
As far as speaker wire goes, there are so many options that will beat the stock or Best Buy wire. I'd suggest sticking with a copper based wire and you can easily find some great used wire on A'gon.
If you start with a good power cord though, you'll more easily be able to hear the differences in speaker wire and interconnects. I'd find out if there are some audiophile groups near where you live. I suspect any number of hobbyists would happily let you try some wire out. As you say, your ears will guide you.
I predict that the 326BEE will reward your efforts to feed it the best possible signal. I look forward to reading your posts down the road. We're in the golden age of budget gear right now, so you can have a lot of fun for relatively little money!
