Yea, that's some of the must-have talents and there are certainly more.

Just to be a bit more clear: there's a few key defense milestones you need with a paladin to make them tank-friendly.. getting uncrushable and uncrittable are both big for real tanking. Without going deep into the protection tree, you don't have much of a chance at either.

So you'll be able to tank stuff where your group can survive both crits and crushing blows... which may be content you don't really want to tank, anyway.
