Regarding #1, you can call a phone number from an email simply by touching the number. You can bring up the menu on the right side of the screen by touching and holding the number and there is an option to send a text message. I haven't tried it in BBM or in a text but it should work the same.
Web address work from a BBM message too.

Regarding BBM updates,you can delete them individually by touching and holding. The menu comes up on the right and you can delete. I haven't seen a way to delete multiples at the same time.
