No, but you can revisit tombs by going to the DNA stream.
I haven't tried this myself but you can try going to DNA from the start menu. Then select a Memory Sequence and click on a mission, it might work.

Complete "Beat Up" missions.
For Assassins Creed 1 No, for Assassins Creed 2 yes.
You can replay levels on Assassin's Creed 2 by pressing start and going under DNA sequence.

I haven't tried it yet, but if you press the start menu and select DNA, then pick a sequence and click on a mission that might let you replay it. I'm not sure though, I haven't done it myself. Just a guess.

Assassins Creed II
Assassins Creed Bloodlines is 5 weeks after Assassins Creed 1. This is what happened to Altair before he dies. Assassins Creed 2 is a completely different thing. The main story is the same but the story of the main characters, Altair and Ezio, are very different. Assassins Creed Bloodlines does not have the Animus in it as much as Assassins Creed 1 & 2
No, they introduced your Brotherhood in Assassins Creed: Brotherhood.
