Congrats! If you don't already have it, print out the sidecar manual on Sidecars.com. There is also a manual that Ural dealers offer. I have it and it's pretty good. It's really an instructor's manual. Probably posted here somewhere as a downloadable link. It has some exercises that you do in a parking lot that will help you get a feel for the rig.
You need to learn how to fly the car. That is key to feeling confident on the rig and also to knowing when you are pushing the envelope and how to recover safely. Can't stress this enough if you plan to ride it without a monkey most of the time.
Too short to ride the roller coaster... now that's funny. I remember somebody years ago saying a friend of his was so short his legs barely reached the ground.
There is a video out there, probably on YouTube of a guy that is very short and rides adventure bikes and vintage Triumphs. He has to put the bike in gear and get it moving while standing alongside. He lets the clutch out, puts a foot on one peg and swings his leg over like a cowboy getting on a moving horse. So two wheelers are not out of the question for you. Besides, it's not about size anyway. It's about attitude.
