If you have problems of to/too type, pronounce them a bit differently, make "too" longer than "to" (or make them even more apart if you already do that), it's a harmless change that may improve your spelling.
You have to change your mentality towards errors, treat every single one as something that is to be ashamed of and correct them as soon as you see them; treat every post you make as you would an official letter. Well, of course do not write it as such, but do take care of the spelling as you would with it. You write a Paper, god damn!
Then, there is interpunction. I am pretty bad at it, so I cannot really point out where it is you that is mistaken, or me. It's not that apparent though, so you don't really have to worry about it.
