Not a big fan of units of 10 wolf riders. You only need to have 3 die and you're taking a panic check. It'd be better to have them in multiple units of 5. I'd maybe just go for 2 units of 5 and then fill the points from the other unit w/ a chariot or other shooting war machines.
On the trolls, 4-wide is going to be a pain since you're playing a horde army. If you can get any practice games in, I'd suggest practicing deployment. Take into account terrain and the rest of your army. Not to mention BSB/General placement. Maybe try 2 units of 4 in 2x2 formation. Less brute force; a bit more utilitarian. Either way you go, they NEED to be w/in 12" of the general for Ld purposes.
Manglers are OK. Pretty easy to deal w/ - magic 'em, shoot 'em, or walk a chaff unit worth 30-ish points into 'em. Boom - dead mangler. HOWEVER...if you can get them to the enemy lines you will be cackling w/ glee!!!
The rest of the list is fairly typical of most O&G lists. Doom divers for armor removal, SOBU for choppiness and a scoche of survivability, boyz w/ brute of a character, token lvl 4 w/ LSH, token lvl 2 w/ scroll, token NG unit as obligatory FDS (Fanatic Delivery System - to quote Ace Ventura, Pet Detective: "FDS people, coming through!") and bunker, wolves for chaff and harassing. Like you said, O&G aren't the most competitive, but, they are a hard counter to some armies out there. WoC players (like myself) dread O&G w/ all the high S hits from manglers and fanatics. We only have so many hounds we can fit into a list!
