Im probably gona get a drawing tablet...?

You don't need Photoshop to operate it. You can use it just as a cursor or a mouse if you'd wish. If you get the Wacom Bamboo Fun one, it comes with Nik Color Efex, Corel Paint Shop Pro Essentials and Adobe Photoshop Elements 5.0. Unless you are going to do drawing as a job, Photoshop Elements is enough.
