Try and get a BFSP dwarf set to go along with your 2 battalions.
You get 32 warriors in each battalion, make 32 as great weapon wielding warriors and convert the other 32 into hammereres see this link:

These hammerers also can double as great weapon warriors when you need them to be.
With the Battle for Skull Pass you will also get some shield warriors you can use as filler if you need too buff units up just put them in the back.
You also get 10 thunderers in the BFSP so use the 32 you would get in each battalion to make that 20 then use the other 22 as great weapon quarrellers
In the BFSP set you also get a cannon and a pony cart which you can convert a cannon or organ gun too with the left over bitz in the battalion:

So for war machines you should have 2 Organ Guns and 2 Cannons
The dragon slayer that comes in the BFSP set is actually pretty good at hanging back with your warmachines and protecting them. Any light cavalry or units that turn up on table edges will get tarpitted 1-2 turns by this guy because of his high
WS and T.
The Thane in the BFSP makes a great Runesmith/Runelord as a shield is a cheap investment for a RS/RL, all you really need up to like 1.5k maybe even 2k is the Rune Smith/Lord and a
BSB, I really like
GWs bsb model but it's special order they don't carry it in stores but it is worth the 1-2 week wait.
You will also get miners in your BFSP set, 8 of them, you can use them as intended or stick them in warriors blocks as filler.
So there you go a solid army...
76 warriors (32 hammerers can double as warriors) or 82 with miners
22 quarrellers-work great as rangers
20 Thunderers-These guys are cool, Organ Guns generally do the job cheaper
2 Organ Guns
2 Cannons
Runesmith/Lord
BSB
Dragon Slayer
Solid start, I highly recommend picking up a Grudge Thrower as well they are the best thing in our army book when runed up. I took down 18 of my buddies blood letters even with the 5+ ward save before he reached my warrior lines,
GW warriors and hammerers are the next best thing.
