I think the scene goes:
(Aragorn walks up)
Gimli: "Well lad, whatever luck you live by, let’s hope it lasts the night."
Legolas: "Your friends are with you, Aragorn."
Gimli: "Let’s hope they last the night."
As to discussing Gimli there are quite a few threads on that already.
Welcome to the 'downs, by the way.
