Get the two reel tank, like most other folks say. And add a few things to your cart:
D76 (but get the Rodinal too, everyone should have Rodinal on hand).
Get more Tri-X.
Get some FP4.
If you can afford it, get a thermometer with a dial. They are easier to read, and harder to break.
You can mix a very economical drying aid with: One part Isopropyl Alcohol (70%) plus four parts Distilled water. No spots! Use it for about ten films, and discard.
You will also need some containers to store your mixed chemicals. One liter plastic water bottles will do fine if you squeeze out the air after adding the chems, and store them in the dark. They're free after you drink the water. Be sure to label them.
Clips, or clothes pin to hang your film to dry.
Have some fun.
