Check out the Wii FAQ by Sarah over on the Budget Board. I read all 216 pages.

Especially check out the first few posts.

In general -
* Don't buy the bundles - Just get the Wii w/Wii Sports $249.99
* Wii Play is decent as you get a 2nd Wiimote + games for $49
(Wiimote is $39 and for $10 the (mini) games are considered worth it.
* You don't need a 2nd nunchuck right away.
