ok, i am level 22 and now have the HL heroic claw. I am wondering what should I get to accompany this thing?
Should I just have a UR handwrap of striking made for when I hit 24 and go 1 in each hand?

Considering whatever you get right now will:
A) be in your offhand thus get half damage
B) get replaced relatively soon
C) be outclassed by level 26 blue 1h weapons

I would strongly suggest just getting a reasonable level 22ish blue for a few silver off a broker.  Then replace it with a level 26ish for a few silver.  etc.

The HL claw you won't be getting rid of until much later on, eventually it will become your offhand weapon at some point in your 30s.  When you can get a new mainhand weapon that exceeds the HL one, that will be the time that it may be reasonable to invest a bit.  Even then I wouldn't burn too many resources until you are ~45ish and really looking and building final gear sets.

Not that I am aware of.
