Here's my two cents: (1) Keep your training corpus around. It will help you recover from a corrupted database and mislearning. In other words, don't delete messages once they are learned. (2) I have a SpamAssassin-SPAM and SpamAssassin-HAM folder set up for users to learn to. Periodically (monthly) I rotate them to keep the size manageable and to reduce the burden of sa-learn rescanning old messages. (3) Only give sa-learn a training folder that has been modified in the last couple of days. There is no need to have it continually scan a mailbox where nothing has changed.
