I would say the best books to learn intro physics from, are Alonso and Finn: Fundamental University Physics. It is closer to Kleppner and Kolenkow, but not as difficult (problem wise), and you can still reference it years later. It does not skimp on the calculus, and almost everything I derived. The only bad part, is that the book has been out of print for some years now. The copy that is available now Alonso/Finn: Physics, has taken out parts of the original second book, and more than half of the third book.
The good thing, is that you are from Uruguay, so I am assuming you can read Spanish very well. So Spanish copies of Alonso and Finn: Fundamental University Physics can be had for cheap. Moreover, if you need an English version, I believe the copyright has expired, so you can legally download it. (I think).
