I already spotted this problem out and the answer was "as of today, there is no place to look at. It's something we gotta work for in the future".
So, there is no real good way to know where to spend your extra energies before having a character to gear up (believe me, makes me sad too)
For gear requirements I love to use the following. You can choose different character levels and thereby the gear level. You can tap on the gear to see its parts. And tap on an ability to see, what's needed there. http://www.star-wars-galaxy.com/HK-47
