Brake line help

[01somta]

I am getting ready here in the next month or so to start bending my SS brake lines, for my wilwood 12.2 front and rear disc kit. I have never done this before so I have a few questions, so please be nice with you replys. I hear people talking about a 37* flare and a double 45* flare, what exactly is the difference. From what I have read I seen that the 37* is prefered. So do I just need the Rigid model #377 37* flaring tool and a tubing bender to do the entire job? What would be a good brand for the bender? Also where is the best place to buy (or should I make my own) clips that are welded to the rearend to hold the brake lines in place. I don't mind welding these on, but I would like to before I get the rearend powdercoated. I posted a pic to show what clips I am talking about. Thanks for everybodies help in advance.
