Hi Turtlehead! Welcome to MobileRead!
Yes, you can have more than one email address. I forget what you do, but it must have been easy cuz I did it.
To delete bookmarks in the stock browser (Ermine) just long press on the bookmark you want to delete and when a menu pops up, hit "Delete Bookmark."
The long press (or tap and hold) is a good thing to remember as it works in many apps.
