Not a problem, I think there was a thread with basic general tips on the reddit. Otherwise, paragonwiki.com should be able to answer most questions not related specifically to the Homecoming server.

1) You can respond to those by left clicking the name of the player, sending a message is one of those options (PST means, "Please Send Tell" btw).

 

2) The Pay 2 Win vendor in Atlas will let you purchase it for free.

 

3) Same as above.

 

4) The friends tab on the chat window will let you do those things.

 

 

EDIT: Forgot to mention that there is a Pay 2 Win vendor in Mercy and a, "Transact 4 Victory" vendor in Nova.
