Check out
http://www.bugmansbrewery.com/, it's a great site focused on dwarfs, very friendly to new players.
Grudge throwers are great now with a rune of accuracy and a rune of penetration. Cannons are great, they need the rune of forging. Organ guns are lots of fun. I use one of each in my 2250 list. Add
BSB and a runesmith with a rune of balance and a few big blocks of troops with great weapons and you have a solid 8th edition list. Just remember that in 8th edition, you won't get many turns of shooting in before you're in hand to hand.
