As the forum says, I need to spend 2000 Wii points that a friend gave me. I have had the Wii since its release, but I rarely play it. Therefore, I have not really kept up with many of the downloadable games that have come out. I know of several Virtual Console titles I am interested in, but I want to get some suggestions on WiiWare games. What do you think? And thanks in advance for the recommendations.

I hear Cave Story is cool

Lost Winds [WiiWare] is a neat platformer in the vein of Okami.

Check out Bit Trip and Art Style games. Also World Of Goo is must if you haven't played it

Send them to me. 
 
Edit: I don't own a Wii.

Cave Story, Bit Trip games are solid, and the Strongbad games are pretty neat if you have any connection to the series/like adventure games.

Not sure about the Cave Story recommendations. Especially since the PC version is freeware

give them to me. 
 
or cave story (although you could just get the free pc version) 
i heard nyxquest is good

Buy M.U.S.H.A. from the VC. 

M.U.S.H.A and Gunstar Heros are pretty amazing.

Cave Story. I have it and it is fantastic (Hell was a bitch).

Sin and Punishment/Cave Story

BitTrip Runner, and Phoenix Wright Ace Attorney in case you haven't played it before.

Whether you wanna spend your Wii points on it or get it on your PC for free, you must play Cave Story if you care at all about old-school style action-platformers. It's amazing.
 
Otherwise, I'd also recommend Lost Winds. It's a relaxing puzzle-platformer. Sonic 4 was decent enough...still not as great as the classic 1-3, S&K, but it's still good to burn a few hours on. Mega Man 9 and 10 are some of the best 8-bit Mega Man games you'll play. And Yet It Moves is another fun puzzle-platformer game and has some of the most interesting use of Wii motion controls yet.
