Well, I did pretty well and had a ton of fun:

.75k Swim: 00:17:21
T1: 00:03:24
20K Bike: 00:40:35
T2: 00:01:53
5k Run: 00:25:01

Total Time: 01:28:17

My total time ranked me 243 of 2050. 31 of 190 in my class. I'm very happy with those results for my first tri. I will try to improve on the times a little for the next one, as I still had some left in the tank at the end. (I'm also thinking about the Olympic distance for next year already...)

I had a ton of fun, and the swim wasn't as bad as I had imagined. Pretty nutty at the start, but once the field settled down and I got into a rhythm, it went pretty smoothly. T1 included a 400m-500m run from the swim to the transition area mostly on asphalt, which sucked... but I was so happy to be out of the water that I didn't care.

In hindsight, swimming in open water the few times I did (with the remainder of my training in a pool) was enough to prepare me. I'm not sure you can really train for the challenge that other swimmers present, and as long as you're comfortable swimming in dark water with waves, it isn't all that bad.
