Hi spankdaddy, I agree with Sebastian that your best bet is to seek advice from other authors on this site. Also you could check out a website like this one
http://www.englishchick.com/grammar/grrem.htmI had a quick look at it and it explains the concepts of English grammar in a fairly straight forward and easy to understand way, without bogging you down too much with too many technicalities. So, it is probably a good place to start to refresh your memory of the basics! Also make the most of the grammar and spelling checker which is built into most desktop publishing programs like MS Word, Open Office etc.
