After Froyo update, I found out several problems.
It drains two times faster than before. My one does. My wife's one is worst (maybe 3-4 times faster and also the phone is hotter than mine).
2) Factory Recovery option
I could not find any factory recovery button from mine and wife's.
3) "Message" icon
My one has no "Message" icon. It has just three icons "Pone/Contacts/Applications" at the bottom of the screen.
But my wife's has all four icons "Phone/Contacts/Message/Applications"
I don't know how to correct these.
It sounds like most of your issues can be found by doing a factory restore on the phone. Settings>privacy>factory data reset. The icons are customizable. Press icon to bring up all icons. Touch and hold on the icon you want on the main screen. You can touch and hold on a blank spot on home screen to add a widget.
As for battery issues, the issue has been escalated to Samsung, and we are working with them to get a resolution as quickly as possible.
Let us know if that helps out!
