Get the widest hammock possible since you are pretty tall. It will allow you a better diagonal lay. Using a pad in a single layer is more challenging so if you plan on using a pad for while go with the double layer. It definitely helps keep the pad in place so when you move around you do not end moving the pad.
Using a pad and a sleeping pad can be very effective but I find UQ's are that much more comfortable. I say if you have the money get an UQ. Pads can make you feel clammy because they act as a vapour barrier and they can give you cold shoulders due to their limited width. A segmented pad extender (SPE) which is basically a sleeve you slide your pad into that has wings you place cut up segments of CCF padding into helps prevent cold shoulder and sides. Even with such modifications, a large number of hangers find UQ's more comfortable with the added benefit of saving space in your pack.
