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 manually connect to the person you want to open a channel with.
i read about "auto-connection in the manpage. i guess you could get away with only the
lightning-cli fundchannel command:
DESCRIPTION
The fundchannel RPC command opens a payment channel with a peer by
committing a funding transaction to the blockchain as defined in BOLT
#2. If not already connected, fundchannel will automatically attempt
to connect if C-lightning knows a way to contact the node (either from
normal gossip, or from a previous connect call). This auto-connection
can fail if C-lightning does not know how to contact the target node;
see lightning-connect(7). Once the transaction is confirmed, normal
channel operations may begin. Readiness is indicated by listpeers
reporting a state of CHANNELD_NORMAL for the channel.
