I don't know if you came across this or not, but for some general cam swap info, Shoebox put together a hell of a guide which includes parts, tools, etc here (#'s 6 & 7)

Re: Budget valvetrain for CC306?
Heres what I did:
New comp 612 springs (comes with locks/retainers)
new oem timing set
new factory hard push rods (n20 had mine a little.... bent)
used 30k mile oem lifters
used 1.6 crane golds self aligning
gasket kit from Combination Motorsports
That was the cheapest I found I could do it and have some reliability.
Stock bottom end, spinning to @ 6700. With longtubes, tune, 4.10s I am trapping consitent 108-109 on stock heads.

Someone let me know if that's correct. Here's my list of parts, complete with part number, price, and vendor information. All these prices are the lowest I could find. Any input would be very helpful, considering I really don't know jack about valvetrain components.

You'll also want some engine assembly lube for the cam, however, you can also use oil to lube the cam if you will be starting the motor shortly after the cam is in. You'll also want a tube of black RTV to seal the front and back of the intake manifold and front cover.

Never noticed if you said it but do you have the supporting boltons to go with the cam? I don't know if there is many but I do know that you will need atleast a mail order tune and some headers. I wouldn't run stock manifolds with that cam.
