Server resource packs

I am using the R3D.CRAFT resource pack on my singleplayer worlds, and I would like to use it on a server I made, which I am the host of. Is there a way for me to use the resource pack, but make it so the resource pack I (the host) am using is not the default, because my friends will want to use their own packs.

I don't have much knowledge in terms of minecraft servers, so I followed a tutorial which involves downloading the files from minecraft.net, running them, and using utorrent to change a certain number (a port, maybe?) to 25655, or something like that. I think he described it as a direct connect server, which requires my friends to type in my IP address to connect to it.

Any help would be appreciated, thanks.
