New Server - Looking for perks

[SINESPAWN]

Hey,

Me and my girlfriend started up a server using LogMeIn Hamachi and Hexxit - and I'm looking for things to add to it, but I'm having trouble finding it / setting it up.

I want to increase the day/night by a bit, so they're not looping so quickly.
I also want to put some radar on the map so people can see who's around them.

I know these probably would fall under mods, but any point in the right direction would be awesome.

Thanks!
