That should be good enough.
I use a 50-39-24 w 11-34
Toe clips No Straps for me.
Take your time and take many rest stops.
I hate hills, but have learned to ride them.
I start in my lowest gear, relax, sit up, Don't look at the top of the hill.
Go slow and easy, change up gears if the low gear was too easy.
