I'm a MUTANT and might guessed wrong

So I ordered my Surly Crosscheck with 105 groupset the other day and I'm VERY VERY excited. However, I'm also nervous because choosing a frame size wasn't as easy as I would have hoped.

I'm 5'8". The guy doing the order at the LBS, who was basically my height, said "I ride a 52cm, you're probably a 52." But he and another person there began debating as to whether I was a 52 or a 50. They decided to measure me. Apparently I'm a mutant because the measuring system produced completely whacky results and we were shortly joined by the owner and cycle-veteran of the shop. He said "You're a 54cm." Person 2 said "No I think a 52cm." He said, "Nope, let's get a 54 and sit you on it."

So they got a 54 (not a Surly) and it did feel good. I ended up ordering the 54 Surly.

However, I've heard that Surly's have a longer Top Tube. So here's the poser: Am I screwed by ordering the 54cm Surly (which has a 56cm top tube)? Should I change my order to the 52cm (which has a 54cm top tube)? What's the risk if the 52cm is too small? Or if the 54cm is too big? Is 2cm even that big a difference? Can it be compensated for in other ways like raising the stem?

Did I just order my dream bike in the wrong size or did I choose the best compromise given two imperfect options?

For touring, the taller choice is better. It will allow you to get the bars higher without having to use as many spacers. To compensate for the longer top tube, just use a shorter stem. Make sure that you are involved in the fork cutting process - have the mechanic build the bike with the fork uncut and then adjust the saddle to the correct height. From there you should be able to determine how many spacers you want under the stem to get the correct handlebar height. I recommend setting the bars up about an inch below the saddle. If the bars are too high you can always move spacers to the top of the stem and eventually cut the fork shorter, but if the bars are too low it is much harder to correct later.
