Update (trevorj): If you are having issues with Maps/Maps related apps FCing, do this: (make sure you are on 2.0.3 when you do this!)
1. Delete “/system/app/Maps.apk” and “/data/app/com.google.android.maps.apk” (the second one might not exist)
2. Reboot your phone
3. Go to Settings > Applications > Manage Applications > com.google.android.maps > Uninstall
2. Market > Install Google Maps

I was about to do a step-by step beginners-type guide using a Terminal Emulator for just this..so let me add to it.
Go to the market and install "ConnectBot" (Or use your current terminal emulator if you have one)
Run connectbot. I used the physical keyboard through this whole process.
Choose "local" in the pull down menu on the left, and Type in a username. Press enter.
It will bring up a command console.
Now type these commands:
su
sysrw
cd /system/app/
rm Maps.apk
cd /data/app/
rm com.google.android.apps.maps.apk
sysro
now press the menu button, and tap "disconnect"
You will now have NO Google Maps installed. If you do(which means you had two installed somehow by trying to fix it), use the application manager or Astro to uninstall it.
Go to Market, reinstall Google Maps, and enjoy!

Mine took two tries from the market..possibly a bad download.
PS: I cannot take credit for these instructions- I found them at AllDroid. Just reposting them here for those that need them
EDIT: Maybe it took me two tries reinstalling because I did not do Step 3 in the quote above?
