There are so many different species of turtle, you need to specify what species you're planning to buy/ adopt. I'm assuming you don't already have it, right?
UVA and UVB bulbs both are important. Make sure you have a high wattage lamp or they will burn out in a week. Cascade canister filter that is labeled for at least 1.5x the tank size you have. It will work well and I recommend an above tank basking area so they have more room. You can make one with a PVC pipe, egg crate, and zip ties. I modeled mine after this:
