I wouldn\'t get too stuck on that idea of trying to find a one stop shop for both. I personally have experimented with various mold making products and resins from different places and companies. It seems that companies that \'bundle\' things together seems to slack on quality with one product or the other. Or they just give you crap altogether.
The stuff that I use now is Micro-Mark mold. I forget the name but it is the same stuff that Herst (sp) molds use. It is quick, easy and seems to last for quite some time if you are nice. It isn\'t the cheapest but doesn\'t require precise measuring or weighing before mixing. Resin wise I am impatient so I pass on really high quality slow curing stuff. I use RP-40 from a local company here in Michigan, you can find them on Ebay as a store.
