Regarding the crimper tool, I'd suggest having a look at the "pass-through" crimper tool and RJ45 plugs rather than the usual crimper and plugs. This is because when I was doing this I did not have a great experience in getting crimps right with the usual tool. It took me several tries to get cables right and even then some connections reverted to 100Mbps from 1Gpbs after some time, indicating a bad/loose crimp.
I thought I'd get better at this with time but after much hassle just went on with the pass-through tools. Life's so much easier now, all crimps good on the first attempt. Admittedly this is just my personal experience, nothing wrong with usual crimping. I know some people are very good at that and their result is always spot on.
I'd agree with this, so far 100% success rate with the pass through type connectors, I tried one with the plastic block and only 7 out of 8 tested on the cable tester.
