RE: crimping tool
I hope I don't come off sounding like a jerk, but why not just solder? I was terrible at it when I first began, but I have gotten much better. It's a good skill to have and you'll get much better connections.
I use one of those butane powered Hobbico torches, but an inexpensive soldering gun from Harbor Freight is a good way to go as well.
Good luck
