i would second the tresemme naturals as a rinse out conditioner. it is really effective.

I would also suggest ultrasheen duo tex as a protien treatment(you get a huge bottle for about $5)

as for hold it would depend on the style. if youre talking braid/twist outs i find that a setting lotion is really effective. i would recommend elasta qp design foam for a really strong hold

if you want something to slick your hair/define waves i would say wet line xtreme gel. that gel is some serious stuff. i no longer use gel but this was the stongest holding gel ive ever used. it is also very drying but i suppose if you found a decent leave in it would work well.
