moving teleport/respawn point

[bmxfelon420]

Hi, I set up forge essentials and changed my home/spawn point to places i want, but when i use /tpx to port from my creative world to the regular world, i'm spawned at a point that's at a wierd place. How do i move those points? (being the points you end up at when you use /tpx to enter a dimension.

Also, can I specifically disable commands? I wanted to disable /tpx commands for dimensions except the two specified.

I am using tekkit lite, with railcraft and forge essentials on SMP.

Also, can I disable monsters per world? I'd like to disable monsters in my creative world. I made this world by making a mystcraft realm and copying my world into the folder.
