I feel like people make a much bigger deal out of micro managing than it actually is. Keep your Fairy on obey, place it (if necessary) and then it's really just like having 3 more abilities on a job. It's not like you're constantly moving your pet or needing to change it's commands. Outside of Fey Wind, you don't even need to worry too much about timers because a lot of their spells are situational.

As for playing on pad, I used to so I can definitely vouch for there being enough slots to play comfortably. You just need to be smart about where you place your most used spells. And while macros are definitely not the way forward, you should macro things like Selene/Eos spells together so you don't need extra slots per fairy. Apart from that, maybe Physick macro'd with Embrace but that's up to you.
