No need to worry Coris, you keep your tattoo. I know this from when I used fantasia very early on. May or may not have to use /lmark to turn it back on, but you don't lose it for sure.

I'm not 100% sure on the other part tho since I don't remember, but I'm fairly sure it starts you out with your current config. Just make sure not to alter race or anything until you get your numbers, because changing race definitely sets all the rest of the stuff to default, but as long as you look at what was preloaded first, you should be able to get those numbers.
