meaning, how do I make my bot join a password-protected channel from within the partyline?
the same goes for invites, how do i make the bot respond to invites, and invites to channels with passwords??
Well you can use need-key, or you can make the bot enforce the channel key (read .help chaninfo and .help chanset) so it will use that key then to join the channel. Or if it's linked to some other bots you can use a script like getops or netbots to make the other bot invite it in the channel. As for +i channels you either need another bot to invite it or someone else needs to do that.
