When looking at hosting companies, check whether they provide cPanel & Fantasico - they allow you to control your site, and also provide out of the box installs for many free packages, including blogs, galleries and CMS systems like Joomla! etc. That way you only need one domain that contains everything. Try
http://www.flexihostings.net.au/ - for $4.50 /mth you can get all that plus a domain name. There will be other options similar, but I have used they guys and am happy. Will leave it to others to recommend their favourite hosting vendor.
