When it comes to Lightroom, I've been rather fond of the TTG gallery templates. These do not come with Lightroom, they're available at the official site at
http://lightroom.theturninggate.net
You can see an example of these (the auto-index version) at

WordPress based photo sites can come in all flavors.
The biggest problem with WordPress themes is the code can be indecipherable gobbly-gook, or well-written human-friendly code that any person can understand and edit. That's one reason I so highly suggest the templates from
StudioPress, as creator Brian Gardner understands the need. He quickly rose from a person with no WordPress or coding experience, to a person that has created some of the best Wordpress themes online -- along the way he surely suffered through crappy code written by others, which makes themes hard to use, hard to edit, and WordPress hard to learn. One of his main goals is to provide user-friendly code.
I don't know much about the themes at
http://www.prophotoblogs.com/support -- but not having demos online makes me cringe. Look at pretty photos and videos of a theme IS NOT THE SAME as test-driving it. This is 2010, and WordPress is well into the 2.9x series. ProPhoto looks to be written in 2008 on the 2.7x series --- and you need to know some things have changed in WP since v2.8. Themes did get broken.
Taking your time to learn everything is very wise.
When it comes to hosting, pick the platform to match your needs. For a simple WordPress blog, a basic Linux package will work. Any of the hosts mentioned here will work:
As a friendly tip, DO NOT GET YOUR DOMAIN THROUGH YOUR HOST. There can be problems doing this, and people do lose their domains because of it. It is better to register with a known reliable registrar. I don't mean
Godaddy either, but somebody like
DirectNIC
I gave up on self-made HTML systems years ago. Once I even customized phpBB to the extreme, and made it into a photo site. In the end, I found Lightroom and/or WordPress to be the best options. Or when selling, to just use
smugmug and pay the $99 annually and do the small profit share.
I'd show you some of my work, but almost everything is currently offline for major upgrades. Just took them down about 6 weeks ago, Won't be done for another month or two. Those sites really didn't have any PageRank, so I don't care about the downtime.
