One thing that you may want to look at for hosting is Mosso. They are based on Rackspace servers, but essentially, it's a virtual server that you don't have to deal with the hosting/config issues ... in other words, you can focus on being a content/web developer.
It's $100 a month and can handle any peak that you throw at it.
Mosso Tell them MacTech Magazine sent you.
