Dish soap (soap in general) is pefectly adequate (in fact recommended) to remove amine blush from epoxy. I had the impression you are just painting over your repair area - not the whole hull. Sorry bout that - I should have read more carefully.
I do not know if TSP will be adequate for the amine blush. It is not good to not assume that the strength of comparative solvents is important (TSP vs soap). It is having the right solvent for the right job that counts... Does TSP react adversely with amines? I don`t know - I doubt it. What I do know is warm water and soap is what is used and recommended to wash off amines.
If you`re hoping to prep the whole hull for paint (not just the repair) I wouldn`t trust TSP for that. It will not remove waxes or silicons effectively enough. Even if you haven`t waxed your boat, it is possible some of these contaminants are present and will degrade the durability and longetivity of your paint job. In a worst case contamination, painting becomes literally impossible.
As for sanding, that will not remove most contaminants, but it gurantees you will drive them into the surface and probably never get them out. So, be sure to clean first, then sand.
The bleach is not necessary.
The volumes of paint you require are here (see step # 13). These volumes are for spraying, so I would add maybe %50 to them for brushing as it tends to add more paint to the surface.
