EavyHunterTournament is what you mean, I was looking for something like that before I found HolyWars it sounds better then HolyWars too sortof because maybe yeah.
Anyway Dedicated server is best I think allows you to run Nexgen and maybe mapvote though maybe thats not necessary for newbs cause they dont know the maps.
XMaps and XMapsRC might be handy if you want to change maps and modes regularly instead of manually starting the server again since you want it to be as easy as possible for the other people.
When I last had UT99 at a LAN party, I was surprised they let me suggest it.
I had AS,DM,iDM,CTF,Strangelove CTF,DOM,Monster Hunt
In reality I think that was too much and needed refining 1000 maps in mapvote is too many I think. Sometime I will definately clean it up though and remove ctf-floridasharkattack that was not a good choice to have there
