3. entering two commands (now that i think about it, maybe the first command wouldn't be necessary if my node would be "older"/ better connected)
Just for clarify, the first command was
lightning-cli connect and the other one
lightning-cli fundchannel. You cannot fund a channel unless you connect manually to the person you want to open a channel with.
By the way, if both peers support dual-funding, they can also use RBF to bump the fee of the opening transaction.
