jacobmorgan well your title tags are standard, i think you are referring to the H1/H2 (header) tags. In that case it does help slightly but don't base your strategy on createing emphasized headers :)
Like Jacob mentioned title tags are standard, just be sure they're short, sweet and to the point.
I would have to say definitely base you posts, content articles around Headers and Bolding keywords or phrases.
Surprisingly, when you set your post's titles and sub-titles with H1, H2, H3, etc. it does let the search engine know the importance. Also, emphasizing keywords and phrases by bolding them is great practice to let the search engines know.
All these little things play different roles in being successful at SEO and every little bit helps with how competitive it is.
