Basically my question is does Bitcoin Core need a bitcoin.conf file (and what parameters) for Armory to send outgoing transactions and overall work properly?

Here's a reply from the dev:

RPC is the broadcast fallback mechanism. Armory tries to broadcast via the p2p layer first, but that one throws a lot of false negatives.

Basically, it will broadcast to your node's peers first and if it fails, it'll be sent through RPC.

- Do I need to add "server=1"? (I noticed this was recommended in another thread when a user reported an issue).

- Do I need to allow for incoming connections? I was always curious about this. I would prefer not too, wallet is just for personal cold storage.

server=1 is required to use RPC.

For the incoming connection, do you mean listen=1?
If so, disabling it wont affect Armory since you can still connect to the network, it' just the other nodes wont be able to initialize connection to you.
