Answer 2

Do you still encrypt or hash? If the second one is SHA1, SHA256, SHA512 it will do fine.

Answer 3

Forget about md5 and clean password hashing!
md5 is prone to collisions, and a password wrapped in md5 can be calculated in a couple of seconds using rainbow tables.
This thing here recommends using PBKDF2 with a minimum of 10,000 iterations (as of 2011). Better use more now.

Answer 4

For php, you do not need to invent anything, you need to use ready-made libraries, for example, www.openwall.com/phpass
