Recording mulitple parts of church service

We’re considering Audacity over our Tascam CD recorder so we can have file access to all parts of our service (message, special music, choir special, etc.) We want one file created for all of these combined sections. Suggestions. Do we just record the first section, hit pause, then the next and so on? Or do we record each section on separate tracks and somehow combine all of those into one file? Just getting started with the manual and online help. Thanks.

Do you intend to do any editing of the recordings or are you just going to export it and put it on a CD (or do you have other plans)?
