LePrevo are good people.
I don't normally use one, but you could look into getting a stitching pony after a while as it will make things easier.
Your fingers will get very sore when stitching, get yourself some zinc oxide tape for taping your fingers (1Inch wide is best).
Leathercraft tools can be expensive, try and get a list and look through e-bay for some at reasonable prices.
If you want good even results when dyeing don't use a dauber (they're a waste of money IMHO) get a few paint brushes they will give a far more even coverage and they'll last you longer.
You don't need to buy every tool under the sun to start with, go with the basics, an awl, some needles, an overstitch wheel, a stitch groover.
Learn about the types of leather and experiment with them.
That should keep you going for a little while.
