Probably the cleanest fix is to let that workspace run a  
non-avoidStruts layout, since avoidStruts is the thing making your  
windows avoid covering xmobar. (And then completely delete the hook  
that floats evince windows.) For example, a smallish starting config  
might look something like this:

     main = xmonad defaultConfig { layoutHook = avoidStruts (Full |||  
Tall 1 0.5 0.03) }

If you wanted to throw on another layout like Tall that covered up  
xmobar's, you'd do something like this:

     main = xmonad defaultConfig { layoutHook = avoidStruts (Full |||  
Tall 1 0.5 0.03) ||| Tall 1 0.5 0.03 }

Because of the parentheses, avoidStruts only applies to the first two  
layouts. Then, I'd switch my "PDF" workspace to the third layout by  
whacking mod+space a few times. (This can be automated, too, with a  
bit of effort. See PerWorkspaceLayouts in the xmonad-contrib  
documentation.)

Good luck,
