Congrats on the bike, Diane will love that bike the more she rides it.
As far as the carb goes, BEFORE you tear into it, I would suggest a full tune-up first! This would include a valve adjustment, cam chain adjustment, new air filter & spark plug, (cheap to replace, & well worth it.) Drain the carb bowl too!
There are several other things to consider depending on how many miles the bike has on it. Depending on your mechanical skill level, you may be able to do most, if not all the stuff yourself. There is not a single thing on this bike that somewhere on this forum someone has addressed, and the more you read, the more you can do, & save $$! (or spend $$, depending on how much you read the customization forum...)
Read around on the forum, & you will find resources for the parts you need to fix / doll it up! If you can't find it, ask. Someone will know. m.
