My advice to you is to plan slowly and map out your fish, gear, and overall look that your trying to achieve. The worst thing in this hobby is to rush because a lot of money and time can be wasted very easily. Your 110 tall is a nice beginner tank and should last you awhile. My suggestion to you for lighting is to look into a fixture that will give you depth since your tank is taller versus wider. Pumps, Sump, Fish, Rock, and peripherals can be a variety of things.
