"POPUP" Messages and other

Hello folks.
I´m at the “final” stage of my mod-projekt and everything is working just fine so far.
There are features i´d like to add but I don´t know how and if it is even possible in the way I want it.
This is what I would like to add if it is possible:
The player enters a Base and a message is displayed like “talk to bartender”.
And: The player is entering a specific system and the message would be like: “dock with bla bla” and a waypoint is set.
And/or: The player reaches a specific objekt in space and a message is displayed like: “Information: bla bla”
And: The player tractors in a specific Item or commodity and a message is displayed like: bring bla bla to manhattan"
AND: is there a way to have the message: “you advanced to level bla bla” in MP?

In general its a question of scripting I guess… and I´m not that familiar with it.
So I´d apprechiate all help and info about this topic in advance…

btw: found a “good” way to have rumors displayed to all players regardless of his/her REP to the base.
Set the rep of fc_uk_grp to 0.2 or higher for all players at startup and give the NPCs that are mentioned to display that specific rumor the faction fc_uk_grp. (works because the rep to that group isn´t displayed on the list and doesn`t change whatever you do…)

Greetings J.R.
