In the first section of the forum, the Welcome section, there are a few things you might want to read.
PTTP is one of Pavel's earlier books. It contains a basic template of 2 sets of 5, done 5 days a week, for two lifts: the barbell deadlift and the barbell side press. It also contains a program called the Bear. Obviously both programs are explained more - the book is an excellent tutorial on the subject of strength, and the programs are simple and effective.
Grease the Groove was written up in an article published in Milo, if memory serves. It's about training frequently - multiple times per day - for strength at a 50%-ish level, e.g., if you can do 10 bw pullups, you do sets of 5 throughout the day.
Easy Strength is another book worth reading, although much of the approach can be found on Dan John's web site. The book has a lot of good concepts in it besides easy strength itself. In my mind, the Easy Strength approach takes the PTTP approach and broadens it, teaching you how to pick other lifts to use it with and how to "roll your own" program.
All three of the things you've asked about focus primarily on the neural/skill aspect of strength and using it, instead of the more popular approach of muscle-building, to becoming stronger.
