Clicking [Optimize] inside the Book parameters gives you this result:
-.#.......|.........+
-..........|......#.+
-..........|......#.+
minimum games=0
up to move=100 (This just refers to the number of half moves that your book has been "written" to play to.
I don't quote understand what you mean by "base to set those numbers", but 0-100 is regarded by most of the community as the default setting for any book.

This question will give you many different answers depending on whom you ask.
For me personally, here is how I have come to look at "draw" books and "winning" books:
"draw" books:
Pros: Draw books are simply books that have either a majority of lines that end to the middle game with a score close to =(=0.00) or a majority of games that end in a draw. The advantage of this is that the book will often avoid riskier lines for ones that are more solid with less chance of losing from that position. This can be helpful when playing against a stronger opponent.
Cons: You will inevitably play many more drawish positions, and the possibility of losing is always apparent.
"winning" books:
Pros: "winning" books avoid drawish lines, and will play for complicated middle phase positions that give your hardware the opportunity to capitalize on the gains your book has made. In my opinion, any book that leads you in the middle game with an eval score of +-(+0.50) or higher is good.
Cons: Books that incorporate only games with wins seems like the best idea...at first. You must remember that the games you win on your computer are only as strong as the hardware you use. Therefore, using your all win book against another book or machine with strong hardware will yield losses for you in the long term simply because their winning games are better than your winning games. (Unless you get your games from stronger hardware!)

You can use any games that you have played on your machine, and incorporate them into your book database. There is a plethora of free available databases out there with good foundations for making books. As a rule of thumb, the newer the database is, usually the stronger it is due to updated theory. Try these games out for size:
