I'm still kind of a noob at complete engine rebuilds.
It can sit for a while. I would use a good quality assembly lube. You can get the assembly lube thru Jeg's, Summit, or any good speed shop. You can even pickup some engine bags, they help keep dust out and rust to a minimum.

As for seating the rings, follow the pistons/rings manufacture's guidelines. Every manufacture has their own preferred method of seating their rings based on their test.

Good luck rebuilding your engine, just take your time and ask a lot of questions, if you don't understand something.
What was the hot tip or the best way to setup an engine 3 years ago, may be outdated and a new better way has been found as new and better materials are being used.
