I don't know if there is a "standard" way to do this, but I
disabled some of the Vim LaTeX Suite mappings I didn't like by
putting the following in ~/.vim/after/tex.vim:

if strlen(maparg("}", "i"))
iunmap }
endif
if strlen(maparg(")", "i"))
iunmap )
endif
if strlen(maparg("]", "i"))
iunmap ]
endif
if strlen(maparg(":", "i"))
iunmap :
endif

Testing for the existence of each mapping before unmapping it
avoided error messages in cases where the mapping didn't exist.
