If you are overwhelmed by the number of templates you can pick from, it helps to go back to the basics: what do you want your site to do? How are you going to split things up, and navigate between pages. Make some very crude sketches, and determine what kinds of things will be on these pages. This will narrow down the range of templates that you need to consider.
Do NOT try to pick the most attractive template. It may not provide the functionality or navigation you need. And by the time you replace the default images in the template with your own photos, it will look different anyways.
