How much follow up maintenance is needed in SEO

[Crownline]

? After my site has been optimized and the key words have been defined does it require constant weekly or monthly updating , or only a few minor adjustments for a few months to increase ranking ?

The answers above are correct, no need to change the SEO on page once its set, Unless you plan to change keywords later. But Link building is a never ending process. Everyday there are new directories coming out or blogs. Writing an article once a week and submitted it to article directories will help also.
