You mentioned an RJ-45 crimper and ends. This is what you use to make patch cables. If you don't want to buy a "Patch Panel" to punch the cables into, you could put RJ-45 ends on them which would require those ends and crimper. I prefer to use a patch panel wherever possible but if you're only running a couple wires, the other method will likely be more cost effective in the long run.
Aside from the punch down tool (ie: google "network punch down tool" for a picture) you will need faceplates and RJ-45 keystone jacks for the outlet end in the wall.
Use either the A or B wiring standard at both ends and do test the cables when you're done.
It matters not how straight the gate,

I am the captain of my soul.
