I do not fully agree to the other post. Unless you are an expert at soldering do not solder your crimp connections. Solder can wick up the wire under the insulation and becomes a weak point that is subject to stress cracking and failure. Use a High quality and the (right) crimp tool for what you have and you will not have any problems. We've been crimping terminals in aircraft and cars for years without problems. What is important is proper strain relief, be sure to tie your wires up so the the clamp supports the weight, not the connector.

It's been a while since I have looked at the old style regulator but if memory serves me correctly then yes, you can remove it all. Your one wire alternator will have an internal regulator and you can wire it either to the bat terminal on your starter or straight to the battery.
I'm not familiar with the harness you got, did it come with all new connectors? What about fusible links? Please consider getting rid of the fusible links if you do have them, they are not worth the risk and danger IMO, convert to a power fuse.
