speeding

Hello!
I'm new to the forum and new to road biking as well. I'd love to get some opinions from those more experienced before purchasing my first road bike. I've decided I want a bike with 105 comps, up to $1500 after tax, something comfortable but also able to go fast and perhaps eventually use competitively (or at least on 60-100 mi rides).
The following are my options at the LBS. Any feedback on these bikes would be GREATLY appreciated! I'm chronically indecisive! Thanks!!!
Trek 2.1WSD-$1350
Specialized Secteur Elite-$1400
Jamis Ventura Race-$1350
Giant Avail 1-$1350
Felt Z85 in a men's model-$1150
Cannondale Synapse 5-$1450
There's also a store that sells Marin and Masi, but it seems they never carry my size (small/51-52cm).
Unfortunately, only two of these bikes were available to test ride (Giant & Felt). The seat was really uncomfortable on the Giant and it didn't seem as smooth as the Felt, but the Felt is a men's with long handlebars, so that's a negative (BTW, I'm a woman). I may be able to test ride others as the LBS gets new bikes, but I want one very soon!!!
Thanks for your help!
