Maybe I wasn't clear about your code.  I thought the goal was something like:

if(showingAll or less than X items)
  sql without a limit
else
  sql with a limit

Why not just skip the query to get the number of items and just put the limit 
in?  If the number is less than the limit then you'll see all of the results, 
if it is more then you'll get the first X results.

The other change looks good though.
