Before doing anything, it would be sensible to cast a glance at the documentation: what are we getting? What can we do with it? What are the pitfalls?
In line with the maturity (or bloat) of the Apache project, there is a stunning amount of this material at http://perl.apache.org/#docs. We started off by downloading The mod_perl Guide by Stas Bekman at http://perl.apache.org/guide. There must be more than 500 pages, many of which are applicable only to very specialized situations. Obviously we cannot transcribe or usefully compress this amount of material into a few pages here. Be aware that it exists and if you have problems, look there first and thoroughly: you may very well find an answer.
