How do you know how many reps to do?
I agree with the others. I would suggest to you to read the book of the “Essentials of Strength training and Condoning” published by NSCA. They have some great information in details on what you are looking for. Of course some online search on this subject will provide you with all the necessary information as well.

I hope this helps.
