Would it be ok to play power chords with just the first and third finger. Like barre the 5th with the third finger and first finger on the root. Or should I play with the pinky. I use the pinky a lot just not when doing chords? Bad habit or fine?

Till' the 12 fret i play it with 1st and 3rd finger, and up the 12th i use my pinky because it gets tight there
It's not a big deal using your pinky or your ring finger...

Anyway.. let's suppose that you're playing an A power chord.. using 1st on the 5th fret on low E and 3rd finger on the 7th fret on the A string is the standard Chord (Root & Fifth), while using your pinky on the 7th fret on the D string will add the root note (octave higher) to the power chord..

Try doing both and see what works for you..
Using the root note in a higher octave with your chord will make it sounds a bit bigger and will add some flavor to it

P.S: sorry for bad english, hope i could help you..
