I am doing the same conversion on my 66 now, I got hoses,pads, and caliper rebuild kits from NAPA, and rotors from rock auto
http://www.rockauto.com/
I am rebuilding my calipers, but they also have the rebuilt ones for $50 with a $75 core charge, the set you have linked includes cores, so you will be fine, so far I have just under $150 in new parts, plus what i payed when I bought the complete take off set up last year,
a quick break down on prices
pads $10 from NAPA
flex lines $15 a piece from NAPA
caliper rebuild kits $18 each from NAPA
