The geometry would suggest that it's a 'true' track bike, which means it follows the European traditions of track bike design, more or less. Of course, depending on your home track, a European-style track bike may not be the best choice. (i.e. if your track is longer and has shallower banking than the tight, wooden 'dromes found in Europe, a longer wheelbase and slightly slacker angles are not a detriment.)

This Rocky Mountain looks like a nice bike but, honestly, I wouldn't buy it until you've had at least a season or two under your belt and you've got a better idea of what you like. Nor, for that matter does it really strike me as being worth close to a thousand. A Bianchi Pista with upgraded cranks and tires gets you a very similar bike for a lot less.

The Steamroller is a perfectly serviceable racer. I see a few of them being raced every now and then. The price of a new chainring, cog, chain, and tires is most likely a lot cheaper than a whole new bike. Don't worry about people thinking that you've showed up to the track on a 'street' fixie. Trackies ride all sorts of beaters and are nowhere near as...style-conscious, as roadies. (That's not to say the guy who shows up on a Colnago C50 Pista with IO/Comete wheels doesn't think he's hot sh*t in a Champagne glass.) You wouldn't be thought of as a poser if you are able to demonstrate even the slightest inclination towards track dedication.

My recommendation: race the Surly. Save your money for nice parts. In a year or two when you have enough to buy a nice frame, like a Felt TK2, for example, you'll also have enough to put killer parts on it.
Alternately, if you decide that racing just isn't your bag, then you're not saddled with a bike that you need to sell.
