Welcome.

Here is a FAQ with a good list of macro commands:
http://ffxiv.consolegameswiki.com/wiki/Macro

They are still missing the sound effects you can built in the group (/p) chat:
<se.1><se.2>....<se.14>

Example for you:
Code:
/micon "True Thrust"
/ac "True Thust" <t>
/ac "Vorpal Thrust" <t>
/p I like sounds! <se.10>
Generally, I would not put combos in Macros. Macros stop when you push another button, so when you get your first jump (which can be used between your thrusts without losing time) it will stop the macro and you will not do Vorpal Thrust.

COnsole users do not enjoy to hear this, but if you have problems with controls and/or Hotbar space:
Invest the 20 Bucks into a simple USB keyboard and mouse.
