Hello there, welcome!
There are plenty of trans members of the RP community here, and the community in general is very open-minded and accepting when it comes to LGBT+ matters. (And to be entirely honest, even dudes playing female characters to be creepers is not a rarity here and the majority of them are still accepted by a good chunk of the community, so you don't even really need to fear being mistaken for that sort of person.) As for the level of your character, it doesn't really matter. However, I would encourage you to progress as much as you can. It's the easiest way to learn the basic lore of the game, and it opens up more locations and outfits/weapons for RP.
Not to mention, you may run into the odd person who will be wont to associate your character's IC strength with your in game level, if that might be an issue.
