I use the F<n> keys to turn these things on and off.  Here is a simple 
example in my ~/.vimrc:

nnoremap \tnum :set invnumber number?<CR>
nmap <F5> \tnum

nnoremap \tl :set invlist list?<CR>
nmap <F2> \tl

For me, F2 turns the list on and off and shows the EOL and makes that 
trailing whitespace fairly obvious.  Of course it only matters in the 
<screen> sections.
