Answer 1

Why not create your own in-app browser? Just put a UIWebView inside a navigation controller then put an address bar and a search bar.

Answer 2

Please see this question:

iPhone - Open Application from Web Page

As for returning to application where you left off -- if the device supports backgrounding (iOS4+) and your backgrounded app wasn't unloaded (due to memory shortage), the app will return the point you left it.

However, you also have to handle the returning to correct point in app yourself, in the cases that the device doesn't support backgrounding, or app was unloaded due to memory shortage: you can do this by storing information about current state of the app before it exits.

This web page has some very nice flow charts which describe app backgrounding and foregrounding etc.:
