What's the best pool to mine? I have  Bitmain AntMiner S3+ 453Gh/s.

I am new so also have few other questions.

1) I am using slush pool but the payout is every one week for like 5$.. Will I even profit?

2) IS there anyother way to profit? I have heard of links to sign up on they pay you?

3) I am a newbie member and I have seen others post where they pay you a certain amount on this site to do certain tasks but won't accept any newbies, how do I rank up?

4) How is trust gained?
