Newbie help with Touch Pro 2

Can anyone tell me the best way to get apps, can I somehow download on home computer then sync to get the app or should i download straight to the phone from the browser.

How can I erase the pre-loaded apps (like sprint football and Nascar)?

What website do you go to for the best free/cheap programs?

When I go to microsoft website on my device it keeps telling me they detect an older version of Internet Explorer and they want me to upgrade to IE 8, can I do that on this phone?

Any other advice, tips, or tricks would be much appreciated.
