"I am thinking solar would be a good thing to put on to keep the batteries topped off if it is not plugged in, any recommendations?"
Not just "topping off" but rather solar should fully recharge your batteries almost every day. I suggest any of the big names, that you do any energy survey to determine your probable AH use each day then multiply by 1.5., buy batteries at least twice that number and that you have at least one solar watt per battery AH.
"changed all the light bulbs to LED bulbs and hope that helps a little bit with power consumption."
Won't help a "little bit." It will hugely help reduce power use.
