Easy there.
No you don't want to go deleting a bunch of stuff.
There is no forums/themes.
In Nuke6.5
it is
themes/YourTheme/forums <-where the forum template files are stored

In the old Nuke6.0 the template files were stored here
modules/Forums/templates

If you ONLY want your users to use ONE theme then all you do is set your Default theme first in Nuke Admin -Preferences then delete all the "other" themes from your themes folder. Once you only hav eONE theme in your themes folder, then the Theme Seleciton wil "magically" disappear from the Your Account page.
