the only thing is please don't make changes to a map then call it your own not right at all. i alway leave the name of the maker be i update to the way i like it to work. some times i see a good thing i like to see how they did it the setting or copy and past a item into a new map i made up.
you can make changes to the setting you only have to do is put a check mark into Deathmatch (DM) and you can leave the check mark in TeamDeath match (TDM) too. will not harm it at all.
