Server/World/Homeworld
Server’s only really matter for WvW as the Megaserver system combines all servers in a region (so EU or NA) in PvE. For RP purposes join another NA server (I’d recommend Northern Shiverpeaks – some really cool people), then fill you friends list with TC RPer’s and join an RP guild. You’re more likely to end up in friends/guild instances so you should still be able to play with the TC folks.

As above, the game has Megaservers. https://www.guildwars2.com/en/news/introducing-the-megaserver-system/
This means that everyone in PvE is thrown together on the same maps. Unless you want to be doing WvW on a particular server then any server in a data group, NA or EU, is fine.
ANet may give it to you.
