You have clearly not looked everywhere, nor have you applied even a moment's thought to your own question. But because I'm feeling generous, here are the answers to your questions:
Haste caps where the GCD gets below 1 second. This is covered in multiple threads including this one.
Crit caps at 100%. Please do not try to gear for 110% crit. Under no circumstances should you ever try to reach 120% crit. 130% crit is right out. There are places where giving 110% is (erroneously) praised; crit chance is not one of them.
Please review the forum rules to which you agreed when you signed up here before posting again.
