Almost 60, what ships should I level up and focus on.

Special Forces Tie and the Silencer aren't farmable yet. and neither are there pilots. (unless I missed something). So you'll want to skip over them.
Tarkin, Vader, Biggs and the two ties are a great start.
You've done good getting Pheonix, so getting their ship is an option.

Starting will a full great thing of ships is kinda unrealistic. Otherwise you could stick with Jedi Consular and Clone Sargent

My reccomendation- Tarkin, Vader, Biggs, Tie, FO Tie, Boba. With Scimitar as a 5th darkside
