I have been looking back at  my various post, emails, and messages.

Some of the word replacements I am finding are insane.

Anyone else having this problem or know how to cure?

I think my iPad has a dirtier mind than I do.  Even in this message I needed to correct three words I know I typed correctly

Happens all the time on my iPhone and iPad!  I just make sure to review what I write first before sending, but you can turn the Auto-Correct feature off by going to Settings > General > Keyboard.

You can also leave it on but choose to get an audio alert when a word is being modified by going to Settings > General > Accessibility > Speak Auto-text.

About one third of provider sites either don't work at all because the flash program is incompatible or only let me see a very small window and prevent scrolling up down or left right.  Any ideas?

This is my first foray in the apple world, and retraining my brain is not easy

Wow, so you get 10s on Iphones too!  Some people may be able to write off visits to you as tech repair.
