First and formost- Welcome.

It's sad to see that hobby shops will recommend a low wing bird as a first plane. It's almost sure the maiden will only last less than a minute.

If you want to fly, I would suggest a high wing trainer type plane. The Super Cub isn't bad to start with, but there are alot of options out there these days.
Stay with something high wing, low wing loading, a slower flying plane. Something in the way of a cessna, cub, the ultra stick.

A sim will help you with some things, however it's best to have some one who has some years under there belt to help coach you. You may want to look into a club.

Park that Spitfire for awhile and go back to it later.
