I write some articles in Latex because it is great for formatting equations, and makes reports look really nice =). Do a google search for specific Latex guides; these notes assume some familiarity.
Personal Observations
As pretty as Latex is, save it for documents that really need it. Sometimes it can be a hassle.
My article template : just copy in the necessary text and compile.
Separating format from content is cool: it allows you to edit easily, and make global changes quickly. The drawback is non-instantaneous feedback of what the document will look like, but in most cases you just trust that the program will arrange it nicely. I'm doing this for my HTML articles as well, writing them in text (.txt) format and doing a txt -> HTML conversion.
latex : latex parser, outputs .dvi
tth : tex-to-html
latex2html : latex-to-html
Both are good, use your favorite
dvips : dvi to postscript
ps2pdf : postscript to pdf
pdflatex : latex to pdf
