The Scott definitely has racier/more aggressive geometry than the Giant Avail. Can you race the Giant Avail? sure. Is it a race bike? IMO, no (and I own an OCR3, the 08 Avail).
You can ride a century on either bike. Some would argue that the Giant's geometry may make it more comfortable from the long ride prospective (it would be more upright, more stable, less aggressive), but it's all about getting a good solid fit for long rides (I ride centuries on my aggressive race climbing bike and do metrics every weekend on it, no problems).
If you want a racier feel Giant's analog to the Contessa Speedster is the TCR Alliance w. So you can get a very similar bike to the Contessa in a Giant package; it's just not the Avail. All three are nice bikes.
My thoughts on buying a bike for the future vs. buying what you need/want/feel best on now.
You may think this is the last bike you'll buy. Truth is if you really get into riding it more than likely won't be.
When I started road biking (coming from mountain only) I bought a Giant OCR3 (basically an Avail) thinking it would be the first/last/and only roadie I'd ever want. It was great for what I wanted at the time (commuter, some fun path rides, general fitness), comfortable, and confidence inspiring (I can handle a bike, but those skinny tires made me nervous until I got some miles on them!).
Lo and behold I liked road biking and wanted something more aggressive. I now have a fancy, quick, aggressive, no questions asked race bike. Honestly, had I bought it first thinking I'd grow into it or might like to race one day I think it would have scared the crap out of me. I still commute on the Giant.
My thought is, buy the bike you are most comfortable on now. Don't settle for something because you think you may like it better later on. Ride it, race it, whatever (none of the bikes you mentioned are unworthy of some beginner races). If you get to the point in your riding where you are really yearning for a more aggressive frame chances are you are going to be yearning for upgrades all around (drivetrain to a standard double or compact and probably up a component level, wheels, frame material/weight, geometry, etc) at which point it's easiest to just get a new bike. Plus you may find you end up wanting a completely different bike than you think you are going to want now (If you asked me 2 years ago when I started what style road bike I'd most likely spend big $$$ on I'd have told you touring over race in a heartbeat, still don't have a touring bike and honestly don't want one).
The Giant Avail is likely to be a little more versatile and a little more forgiving than the Scott, so I'd say start on that since you like it and the shop.
If you really want a race bike the Contessa is the better option all things (FIT!!) being equal (but the Giant TCR Alliance could be in the running then as well).
Handlebars, saddles, stems. are fixable. Talk to the shop and see if they are willing to work with you on a wider set of bars if you don't like the stock ones (many women like/need narrower bars than their male counterparts, so I wouldn't be surprised to find narrower than average bars on a "women's" bike).
