I just noticed I've gotten airdrops of a bunch of Runes because of some Ordinals I was holding. I saw some horror stories of people who tried to sell their Runes and ended up losing everything else, where can I go to read up on these Runes and if/how to sell them safely?

BTC not like Eth. Just inscribed sats. I haven’t heard of wallet drainers. Go to ME

I think magic eden is easiest but also don’t quote me on that.

Are you referring to pre-runes or actual runes? Former there isn’t the drain risk to list as no smart contracts but most are worthless now. For actual runes, there have been issues on marketplaces like unisat due to UTXO management.

Unisat ship quickly but given runes are early, stick with ME and Xverse for now.

Check ordiscan.com to see what you received and try to find the projects X handles for info. 

Magiceden.io definitely the easiest way to check portfolio and get valuations. Selling is easy but can be done how you received them (per lot), ME also support splitting lots.
