I got most of my stuff from Texas Speed & Performance, they won't just sell you something because you say you want it. I was getting a set of head gaskets, and told them that I wanted .030 gaskets for a set of heads that were milled .030, and they talked me out of it, saying that they wouldn't be comfortable with the Piston to Head clearance. So they're also genuinely concerned for their customer's and their customer's builds.

Give them a call and they'll get you what you need.

You can put the PR's, springs, and lifters in, but I'd wait and do the cam at the same time too. no reason to do the same work twice.

Why not just do the cam and springs?

Pushrods, springs and lifters are not going to gain you anything. They just support the cam upgrade. . .

Don't forget the head bolts and gaskets. **** adds up.
