Hey guys.. Just started hordes. Not too sure really whitch way to go with these guys... I mostly play 40k, so it's hard for me to choose between the different units and warbeasts.

This is what I have so far

Ironhide.
Dire Troll Mauler.
Dire Troll Blitzer.
Troll Axer.
2 x Troll Impaler.
Unit of Champions.

Anyone know what to add or give me any hints on how to play the Trollbloods?

You have a decent starting army as is (the starter set is actually a very good starting army already). It allows you to build a few interesting lists from 350 to 500AP. I'd suggest you keep it like that, try to play a few game to get an idea of the style you like most, and then decide on what to add. A few people usually show up on Tuesday nights.

If you really want to get new models immediately, you may want to purchase the very useful Fell Caller, or perhaps to look for another warlock (the 5 of them are very different in playstyle). For general info on models, you can check out the trollblood section of battlecollege.

I play trollbloods too, I'm not a very experienced player and every game I played ended up very different from all the other ones. However I own quite a few models, so once you've had a chance to try your current models I'd be more than happy to let you borrow mine so you can taste other troll flavors.

I have the dire troll mauler extreme model unassembled. Would either of you be interested in it for cash or trade for confrontation stuff. I also have champions, hoarlock doomshaper, grissel, 2 spearthrowers, axer, dire troll, and the weird looking minion with a big spear and shield (kinda looks like a predator).
Just thought Id mention it.

I already have two extreme trolls, I think I'm good :)

As for the rest, I'm afraid I don't have the quid to buy any more model. If nobody here shows interest, I suggest you try the gunbunnies group.
If you don't manage to get rid of them by the time I solve my cash issues, I'll be happy to take your champions. But don't hold them just for me...
