Photography website/blog

hey,
I just bought my domain and hosting. I chose fatcow hosting with WP as a template. I want to turn it to as a photography website that includes portfolio, contact, about page and with a blog intergrated with it. I just want to do this with using just WP. I have seen people done that but I am not sure how to do it myself. Should I just buy/use a theme and customized it myself with plugins? And if so should I use a regular theme or photoblog theme? Should I make it myself with just plug-ins and stuff? Thanks.
