I'd avoid those cheapo ebay light kits, they're cheap for a reason. Kits suck, buy what you need, your money will go further. Also, don't rule out renting. I rent A TON, and only own a few basics.
Remember, lighting is all about light control, not using a billion light fixtures. Look into getting a few flags. (You can improvise with black foam core also)
500/250 watt photo flood bulbs on a dimmer, and silk china balls will go very far.
(You can find them cheaper)
Go to home depot and get a piece of 8x4 foot bead board chopped in half. Really cheap and effective bounce.
I have a few of these. Cheaper, but not total junk, they do the trick if you take care of them.
Lowell pro lights are decent and cheap little lights and are good to have in your arsenal. As well as some Lowell omni lights, great hot light to bounce off some bead board. You can find them on ebay for cheap if you are patient.
If you live in a bigger city, hit up your local grip house and see if they have any old school 1k Mole lights sitting around that they'd sell ya. You can usually grab 1ks for $150-$200, sometimes cheaper. Buy a softbox for it and you have a great key light for cheap.
BUY USED WHEN YOU CAN, YOU WILL GET MORE FOR YOUR CASH.
Also, lighting is creative, there is no right way to light a set. Use what tools you have, and remember natural light can be shaped very nicely for cheap.
Hope this helps.
