Take a look at this checklist. It helped me get apps submitted:

Here's my guesses on fixing your 3 issues. Correct me if I'm wrong on any of this guys.

1. You need to add your icon as a 57x57 .png file, and make sure that the icon value in info.plist matches icon.png.

2. Set your minimun OS requirement in info.plist or the build settings to be HIGHER or EQUAL to OS 3.2

3. Go to the developer provisioning portal: http://developer.apple.com/ios/manage/overview/index.action

Get a new Distribution certificate. You need to code sign with a distribution certificate in xcode, creating a release version. Then it won't give you an invalid signature message.
