Beastman100,
You have your work cut out for you but you have come to the right place. First of all you are already doing the most important thing you can be to rank well in SERP's and drive more traffic to your site which is creating fresh quality content that keeps visitors coming back. Don't ever stop doing this.
You should also do some on-site SEO by first finding keywords that you would like to target. You can use a tool like Google Keyword Tool or something similar to get keyword ideas along with data related to them. You should also use some type of keyword research method to determine which words and phrases are best to include in your copy. Ideally you want words that are highly relevant but not that competitive. Sometimes you may have to compromise though. Once you have your set of keywords, build a page around each one including the word or phrase in the copy of your website, in title tags, meta tags and alt tags. When you write your articles you can use the same approach.
There are also off-site tasks that you can perform to drive more visitors from organic listings. Set up an account with Google Webmaster tools if you have not already and submit your site's URL. For a new site, tasks such as creating a sitemap and submitting it along with your new domain to the major search engines, creating external properties such as wikis, free business listings, and submitting fresh articles with linked keywords to web 2.0 properties will all help your cause. Social book marking is also a good tactic. Create links to these web 2.0 properties from social book marking sites.
Keep up to date on industry news by reading the blogs and following the social media accounts of industry leaders. SEOMoz is a good one along with @randfish - Rand Fishkin the organization's founder. Another good resource is SearchEngineLand.com and you could follow @DannySullivan - Danny Sullivan, the website's Editor. Matt Cutts -- @mattcutts who is head of the webspam team at Google is another great resource.
This should keep you busy for a while and as you get into these tasks you will find more things that you can do to help improve your traffic.
