DL, your equipment should be fine for starting out.
Most of the portraits I shoot are at f8, unless I'm trying to get fancy and artistic.
So both of your lenses should do that and be relatively sharp. At f8 perfect focus isn't so critical because the 60D can't be focus adjusted.
The problem with the 50 is it will be fine for headshots and maybe(?) 3/4 shots but you need a LOT of room to get full body or more, so the zoom comes in handy for that.
I use mostly an 85 1.8 and a 24-105 f4 when I need a wider shot(on FF).
But shooting available light might render your zoom too slow indoors, without a speedlight, or adding light, or you'll have to crank up the ISO. Good luck

Your lenses are more than adequate. The biggest challenge for beginners is understanding how to light their subjects. I would suggest setting up a sitting area (studio-like) in a gage near the rolling door. This way you can get diffuse complementary lighting - soft, smooth, no hotspots and nicely directional. If you need to add more light to the other side away from the open door, use a large reflector - I use white rigid insulation board or a folding reflector.

At some point in time you will want to use flash. The rule that will get you the best results is never point an unmodified strobe or flash at a subject - best is bounce, next would be a softbox, shoot through diffuser, an umbrella - shoot through or reflective, etc. The goal is to keep your light source as large as possible for the most complimentary light. Study the basic portrait lighting setups - you can find them by googling for classic portrait lighting.
