Yes, you can take the .gpx route files and put them into various tools that generate profiles, such as Topo or RidewithGPS.com.
Sort of, you need to join Adventure Cycling to access the GPS files. It's not as bad as you might think, because one membership (I think it's $25/year) will let you access all the AC routes.
If you're interested, one way to fix your 1:1 low gear is to replace your current double with one of the SRAM mountain doubles. I think that'll let you get down to a 24/34 gear. There's still some 10%+ grades, so you'll need to pack light, get in shape, and - perhaps most improtantly - be prepared to walk anyway. The good news is that most of the really steep grades aren't too long.
