Welcome to the QB from SE Michigan. I do a lot of hand quilting. This includes the avatar under my name. The entire GMFG is hand quilted. I do not use a thimble or finger guard. Being left handed I find them very uncomfortable.
For a new hand quilter I would recommend something called "Tiger Tape" the marks on the tape are spaced exactly the distance you want between stitches. When I first started hand quilting it was the biggest help for me. The owner of a LQS suggested this to me and it was a life saver. I still use some from time to time when I am hand quilting for the first time in a while.
Needle size I usually use a smaller quilting needle with a slightly bigger eye. I find them easier to 'rock' back and forth and pull as I go.
And last of all you are in the right place! Just jump right in and enjoy the fun! Ask any questions you may have and share all your accomplishments here too.
