32gb will be cutting it pretty close. Remember that you'll want some "free space" also, say 10%? Since it will be coming with the ssd installed already , most of the little things should be taken care of for you. I'd check and see if your hibernation is turned off if I were you. Also, I'd consider just canceling your page file for C. If you're a "regular" user you shouldn't need it with the amount of RAM installed. (always room for more though!
And yes , you are entirely correct about the amount of crap/bloatware that will come with your Toshiba. I owned one...... I know
...... you'll love your machine after you get all that stuff cleaned up though, I'm sure. Just follow LittleJay's link and all will be revealed to you
