I'm the last person to discourage someone from home gunsmithing, as it can be a lot of fun. However, the parts you linked to are low quality. They can be built into a shooter, but without someone who has experience to guide you through it, you will find that parts that should be drop in are not, and you might find it impossible to figure out why. Also, by the time you have toold and the parts that you linked to, you could have bought a good used Springfield, and even an ORM Colt 1991 if you look around.
You would be much better served to find an already assembled pistol, pick up some books/vids, and do a modification here and there. That's just my opinion, though. I've put together a few 1911s, and I started by doing small projects like a trigger here, a safety there, etc.
For a basic beginner's book, I would recommend Hallock's 45s. From there, there is a well regarded book by Jerry Kuhnhausen, called The Colt .45 Automatic A Shop Manual. It is kind of the bible to .45 guys. There is also a more advanced volume two to that book.
Anyway, good luck.
