Yes, that's good.  u helps you catch typos in variable names (that otherwise just expand to nothing).

If you think there might be times when e stops your script and it shouldn't, you can always catch 
the error return and do the right thing from there.  If you don't know what will cause an error or 
you don't know what the right thing is then exiting (via the e) is probably your best choice.

FWIW
