Hi...Since you have updated to Froyo, let us know if you are based out of India or somewhere else and if in India, please let us know the procedure to update so that we can enjoy Froyo as well...thanks in advance!!
Yes, I am based in India - Mumbai. As mentioned in my post I updated using Kies.

You cannot move all the apps to SD. Some apps NEEDS to stay in phone memory for them to work, and thus the option "move to sdcard" remains non-highlighted for them. Also, you should not move apps that have their widgets placed on any of the home screens.
Check out various move2sd apps in the market for better management of apps. I personally use apps2sd free.
1. in my experience, upgrading to FroYo typically increases the battery life. (means, it should last MORE). It could be that you have not tweaked settings after upgradation. Check if any unwanted services are running by default, such as GPS, Auto-sync and such. I am sure you will find more tips on increasing battery life somewhere in this forum. Since you can see which programs are running again n again, (when you use ATK), take corrective steps accordingly. Simply uninstall apps that you don't use or very rarely use. (Google Gesture Search is one such app...I installed it just for testing n show-off but rarely used it, but that app used to re-start everytime, so uninstalled it)
2. About battery widget..have you moved the app to SD card? As already said, widgets don't work if the app is on SDcard.
3. Have you tried Custom FroYo ROMs? They typically are optimized for offering better battery life. I use Kyrillos' ROM and like it immensely.
I would advice you to check the official xda forums to know all the basics on custom ROMs, rooting and other things.
There are apps available in the Market which will prevent auto-run of other apps at the start up. Search for autorun killers and try installing and testing the most popular ones. As said already, simply uninstall the apps that you don't use. Also, personally, I wont recommend using any anti-virus app. Its simply not needed.
