Where do I even start?

So I inherited this truck and I really want to do a restoration on it. My grandfather restored it back in the 90s and now he wants me to have a go at it. As he got older the trucks condition declined and it lived at our cabin for a majority of my life. Its the 72' Sierra Grande with the 350 in it. I'd love to do as much of the work as I can, but I've never tackled something like this before.

It runs and drives, but it could definitely use a tune up. I bought an haynes owner manual and I have some other books to. I just don't even know where to begin. How much is this going to cost? I have about 15k to put into it.

Any suggestions for first time restorations would be awesome!

Thanks.
