Nikon Sb 26 or 28, or vivitar 285 HV. they are relatively cheap and work great.
Yonguno Rf 602's. Look em up on ebay, they are pretty cheap and have awesome reviews. 100+ foot range, cheaper than pocket wizards or cybersyncs
depending on what flash you get you might need to get a special cord on ebay, probably like five bucks but the RF 602's have a funky connector.
a 6 or 8 foot manfrotto stand from B&H should serve you well. they are built solid and will do what you need them to do for $25-30
