Bicycle Mechanics - Can anyone help me spec a surly troll build?

I want to have my lbs build a surly troll. I'd provide the seat, pedals, and handlebars.

My bars would be trekking bars. they are Mtb size. Can you guys spec other things for me? A compact double in the front-9 speed in back. Shifters need to be simple and reliable.

My main concern is the wheels. I want to ask for a tough set of 26 in rims and a nice set of commuter slicks. I would put lots of milea on this bike.

So if you can give me ideas on the wheels and a low cost drive train/brake set/gear setup I would appreciate it, as I'd like to make good choices. Money is an issue. The frame is around 500, and I'd like to get the bike built for another 500 if possible.

Thanks!

Need a lil more imput.
What do you want on the bike?
Are you trying to set it up like a road bike [ you mentioned the compact double ]?
Rim brakes or disc brakes? Disc brake set up will cost more, as will disc compatible wheels.
What kind of bb, as it affect the type of cranks you'll use and their price?
See what build kit options your LBS may be able to get and price them out.
Otherwise I think you will blow thru your price range.

I actually prefer cantilever brakes, I believe the troll supports these. I guess I'm confused about the front chain ring. By speccing a compact double, I just meant I didn't need a triple - but if a triple is low cost - then by all means - no problem. I'd like more mountain components on it. I'm going to use it on street as a commuter and a tourer - but my handlebars are going to be nashbar trekking bars - which have a mountain diameter for levers and shifters.

The bb thing - I'm not sure. I'd like longevity, sealed against elements, ease of replacement, and all that 1st and foremost. Something standard - nothing off the wall. Don't really care about weight - (unless you have 2 that all things are = one is much lighter, etc). My LBS is really small and does not have 'build kit options' asfaik.

I was trying to get price down by buying frame and wheels from him (although I'd like input on which 26in wheels/hubs would be best loaded and used a lot). Pedals, I'd like a dual platform/clip in setup where I can use regular shoes as needed. I have the seat already. Would love 26 inch 'thin' fast street tire thoughts, etc.

So, I'm on a 'budget' of sorts. Looking for practical components that are easy to surface. Weight is not a primary consideration, so you don't have to steer me to ultralight/ultra expensive parts. I have no brand loyalty, for instance I was considering "Nashbar" rear and front mountain derailleurs - if you guys think they are good, etc.

Thanks for your input.

Brakes forget cables.. My Current favorite : Magura HS 33 The hydraulic rim brake
http://www.bikeman.com/BTI-MU7811.html

fits on the Brake bosses for cantilever /V brakes ,
but does not use it as a pivot, as the pair of slave pistons move in a straight line.

A More compact double : Velo Orange, 46/30. get the BB from them, too
they will get the right one to match their stuff
with 12t cassette cog, high is covered, 30/34 should work for low.
Bar end shifters.. converted to Thumbies with Pauls adapters.

230$ brakes are wayyyy out of my price range. Like the velo orange suggestion.

Your LBS is getting the frame for you, right?
They oughtta be able to get a build kit from the same distributor ... it would be a group of components at a slightly lower price than if you bought all the components piece by piece.
Ask em before you assume that they can not do it.
Also whose goin to do the build [ assembly ] ... you or your LBS? That may cost as well.

Parts suggestions:
Headset [ all threadless ]: FSA, Cane Creek or Aheadset.
Stem: Salsa, Kalloy or Zoom..
Brake levers: Tektro 354AG [ cantilever and v brake compatible ].
Brakes: Avid Shorty 4's, Shimano BR-R550 or Altus CT91 [ cheapest and hardest to adjust ].
Wheels: 6 bolt disc hubs to Sun Rhyno Lyte or Sun CR-18 rims. Rhyno Lytes are more expensive, duarble and wider [ take a 1.5 tire or larger ]. CR-18's will take a 1.25 tire.

Shifters: SRAM twist/throttle shifters that are Shimano compatible will be least expensive. SRAM or Shimano triggers will be more expensive.
Chain: SRAM PC951
Cassett: SRAM or Shimano 9 spd, entry level model.
Front derailleur: SRAM or Shimano mid range model that takes a 46 or 48 tooth chainring.
Rear derailleur: Shimano Alivio or DEORE.
Bottom bracket: Shimano cartridge square taper bb
Craknset [ all have replaceable rings, all should be $75 or less ]: FSA DynaDrive, Sugino Impel 150X or Shimano Alivio M430 series ].
