Hi,

sorry, I do not know...

>> 2) I read somewhere that each table must have one primary key? Some of

django adds one to each model, if you do not do it called "id"

>> 3) Is there a limit on the number of Foreign Keys in a table?
I do not think there is a limit, but do not know

>> 4) How often would I need to patch and/or upgrade Django? And is this

depends on your OS - if you are on debian: apt-get update / upgrade if it is a 
minor update  - they
cept a lot of focus on backward capabilities
you may consider using south, if you have a lot of db changes yourself for 
migrating the db and the data

regards

Hinnack
