Welcome to MTF! You'll find all the help you need here as there are some very dedicated Gravely nuts around here.
First, have you found www.oldgravelys.net ? All the manuals you could ever want are there for your viewing or download.
Second, we want to see some pictures of your machine! (You'll find we love pictures and they also help with diagnosing any problems you may encounter and sometimes the keen eyes of other members pick up on things before they become a problem.)
Paint, since you have one of the later models I do believe it is still available through your Gravely dealer in a rattle can. Matching original paint is an often debated topic but I use Ford Red for touch ups and am pretty happy with the match. Maybe someone can point you to one of the previous paint threads shortly!
