The simple answer I have always used is that Before triggers should update the actual record(s) that called the trigger while After triggers should update related objects. Example: A Case is edited and saved, which causes the Case Trigger to make two updates to the Case itself (Before) and add/remove Milestones and Entitlements related to the Case (After).
This a general rule and is not without myriad exceptions, but it tends to keep me out of trouble more often than not.
