When using Asterisk and SER together, should SER place calls to the PSTN, and Asterisk only deal with "special features" such as voicemail, queues, autoattendants, etc? Or should SER be used ONLY as a proxy/registrar, and all calls be routed to Asterisk so that Asterisk places the calls to the PSTN?

That depends a lot on your particular setup, Nick. If you're doing a pre-pay by the minute scheme, there's no way for SER to cut off a call when someone runs out of minutes, so you'd want to forward calls through something like Asterisk B2BUA. If you're doing a monthly scheme, you can set flags based on database values and SER is perfectly capable of shunting the calls to a PSTN provider.
Some people will also use Asterisk to transcode (convert from one codec to another) from a common VoIP codec to one that their PSTN gateway understands.
It can be done a lot of different ways. :)
