Torie, what do you mean by "Kodak B&W 100"? Do you mean T-Max 100? Anyhow, in case of 'regular' b&w film, as opposed to chromogenic [C- 41] film, here is what you need:(posted 8208 days ago)B&W Film developer [use T-Max Developer if you are developing T- Max film]
Stop Bath
Fixer
Fixer Remover [somewhat optional, but cuts down on the washing time]
Photo Flo [also optional, but highly recommended so your negs don't show water stains] [Photo Flo is a Kodak product, other companies make similar stuff]
I recommend you buy liquid chemicals that you then dilute with water. I find them easier to use than powders. Every photographer has their own favorite brand/concoction of the above chemicals. So, you will get lots of different answers. However, you can't go wrong using if you buy Kodak, Ilford, Sprint, Arista, or any other brand names of the above for starters.
