I always go with the combo upgrades, in fact when 10.7.3 came out, there was a problem with the patch update and the combo was the only way to go. Personally, I would remove Magic Bullet, if there’s a serial tied to an online activation I would deactivate that. Install Media Composer and re-enter the serial. Again, not everybody does this and I’ve heard of it working out, but I tend to be a little crazy about that stuff.
I’m using 10.7.3 and nothing notably different from 10.7.2 but it works fine.
