Here are places to look for words:

what does □ mean?

This is a font-failure on someone's end. I see a □, is that what you wrote? When your browser comes across a character for which it lacks a font, it replaces that character with □. ' ' ∅ ä ì are the only potentially non-standard characters you might see in Na'vi (although ∅ isn't used in actual texts). Do any of those appear as □ for you?

Well, for good night I know some people like to use sìltsana txon but methinks that would be literaly a night that is good, I go for txon lefpom livu ngar

[Eyäzong]

Said people are wrong. You're along the right lines. Frommer has given us the phrase "txon lefpom" which is essentially an abbreviated form of yours.

Also, in copula + dative constructions for "have", the lu comes first in the sentence.
