What parts would I need to lower my 2000 Toyota Tacoma...?

[nsm3919]

I have been wanting to lower my truck for almost about a year now, I really don't know what to buy in order to lower my truck, I know for sure some coil overs, new shocks cuz mine are bad, but what else would I need? If you guys can be detailed about the parts that would be great, but if not please let me know what I would need? Thanks
