There's kind of a lot of questions hidden in here, so it's hard to know how to approach this. But let me just say one thing unequivocally: if you have a static website with pages that are difficult to update, you are doing it wrong. A website that is easy to update needs to be your first step because you need to keep it fresh and you need to be able to try different ideas and measure how they perform. Unless you love web design you should sign up for one of the many great sites like squarespace.com or aphotofolio.com and move on (here's why).

I think Lightroom is a terrific tool for wrangling photos, but it's hard to give concrete advice because there are so many ways to work with it. I like to use keywords and star rating in concert with smart collections to focus on my favorite work from certain locations. From there it's easy to just export and upload to a gallery if you have an easy-to-use website admin interface.

As far as getting your work out there, 'out there' doesn't really exist. You need identify specific people and organization who will pay you for your work and develop a concrete, actionable plan to reach them. If you want to work in a crowded field like fine-art photography or travel, you are competing with people who are sending out mailers, arranging in-person meetings, getting the right blogs to showcase their work, and trying to be very active in the community in which they hope to work. A good, current website is essential, but it's just the foundation. Your work is terrific, but the competition is committed and good at the level your work deserves to be published.

So stop thinking about some vague 'out there' and start identifying real, breathing human beings who you should get to know. Once you do that you can evaluate the different avenues like social media, conferences, direct mail, etc. to reach them.
