Many art programs have a free trial, usually 30 days, so be sure to have a look for one before investing. 
The only program for drawing that springs to mind aside from Photoshop (which is kinda pricey) is PaintTool SAI. Lots of my friends have it and swear by it. I can't find where to buy it but last time I checked it was around £45. There are also lots of free downloads if you don't mind that.
As far as tablets go I've only tried Wacom, but I highly recommend their tablets, they're really great and easy to use.Â
