For your first time out, bring someone with experience. Don't go alone. Be realistic and safe. Focus on smaller and better hikes. Also, as far as high country and the end of October, it's shoulder season...you can be blessed with nothing but bluebird days, or you can get caught in a blizzard.
You also need to be aware that, because of the season and possibility of snow, you can't even park overnight along Tioga Rd or Tuolumne Meadows...they'll tow you before morning. Shuttle/Bus service up to and from Tuolumne are also either limited or long since shut down for the season by then. Most of the first-come, first-served campground outside of the Valley will be closed for the season in September, too.
If you want to test yourself, see how you do, learn the drill...you should get a permit for the North Rim of Yosemite Valley: hike up Yosemite Falls, go over to North Dome, then head down to Snow Creek and exit back in the Valley at Mirror Lake. Bite sized, lower elevations, you can bail out if you need to, some good places to camp, and some incredible views.
It's fantastic that you want to get into backpacking, but you want to make sure it's a success, and that you want to (and are able) to do it again. Doing it safely, smartly, well , and having fun doing it, entails a lot more than throwing on a pack and walking.
