I'll toss out another option...
For the amp, call Gabe Velez and have him build you one of his Mag-SE03 amps (
http://members.tripod.com/~gabevee/ ). These are single-ended EL84 amps that are based on an old Magnavox circuit and put out about 3 watts/ch. I've never heard any of Gabe's amps, but he's been around a while, has a good reputation and is a very nice guy. $299 (I did talk with Gabe last winter, and he said the SE09 looks very much like his 300B amp, pictured at the site...except it has skinny el84s instead of big ol' 300Bs).
Another option is to call Boris at Vista Audio...he has offered some single-ended EL84 amps on his site in the past for about that same price, give or take. Don't know if he'd still build you one, but he's another one who has a great reputation for quality tube amps for not much money.
For the speakers, I've heard and read favorable things about Tekton Design. He is based in Utah and builds single-driver fostex models in various shapes and sizes. His smaller version using the fe127 driver goes for under $300 I think. He sells on ebay...do a search for Tekton Design.
For cables, buy a pair of 1m RCA DT3A interconnects (try ebay again). Speaker cables...orange and black Home Depot extension cord.
