How do you implement UI for the non computer savvy?

Question

I have been support a web app that is used by a user base who's age range if from 40-65. The app is very good and has the latest ajaxy stuff etc. What we would now call very user friendly and responsive. I am amazed as to how this app is not so userfriendly for that user base. I was told that some autocomplete features make them disoriented!! Also, a lot of accidental clicks happen, they sometimes say "its not going thru!" then I realize that one of required check boxes were not clicked. I hope I made the scenario clear.

Could someone provice me resources/tips for this? Is not so much as an accessibility issue.
