Just got a TT, overwhelmed by what I need to fill it :)

If possible, try to spend a night in the driveway. It will help you get familiar with your new TT. It is getting cold, take warm clothes. Make sure you can use the furnace and hot water tank.
PS: That's a lot of trailer for an F-150. Check into the other threads here, about payload, tongue weight, etc. It doesn't take much to add weight, quickly. Don't forget to add water, fuel, passengers into the equation.
