This, to me atleast, is a common practice.  I like to do as much string
manipulation in MySQL as possible, but unless you have tons of data
being loaded, or very heavy traffic, you should have no problem
eitherway. 
However, if either of these is an issue, you may want to look at some
type of cacheing.

Templates wouldn't help here - the data still needs to get fetched and
managed.  Just write clean code, paying attention to performance tweaks
where possible.
