It could partly be stiff links (see http://bicycletutor.com/stiff-chain-link/ - loosening by hand is enough). Otherwise yes, riding will make it shut up eventually.

Yeah, that'll be the wet lubes special dirt attracting properties, sorry!
Should be ok without lube, bear in mind the sprocket and chainring are worn in and the chain won't be, so it might sound like shit for a while while the chain sorts itself out (well, it did last time I changed my chain but it wasn't a great chain).

I had the same thing when I put a new chain on it. Drove me mental trying to work out what it was, but eventually it just shut up.
