OK so I need to export them to the IPAD directly ?
Just export them to a folder then put the images wherever you have the ipad set to look for images.
If I cannot export directly into IPAD then do I need to export to new folder and then sync?
I don't think it's possible to export directly to the ipad but there is no reason to anyway.
Now I will have two locations with the same photos, one with exif and one without?
Your lightroom library is the primary place for your images and it's where the full resolution images will reside. When you want to put new images on your ipad export them from lightroom at the appropriate size for your ipad (retina vs non-retina) and without exif data. Once the ipad syncs you can delete the files you exported from lightroom as they are on the ipad now. Should you ever need to add them again you can re-export from lightroom.
No matter how many times I sync pictures to my IPAD they never sort by Date Taken, it is alway by the METADATA DATE from the last adjustment?
I believe it is from the last change to the file. Been a while since I worried about it but if I remember correctly if I exported a group of images from lightroom then made a change to one of them in photoshop and re-saved it that would change the order.
Also keep in mind this info may changed with iOS7. I don't think it did but I stopped using the built in camera app once I updated. It's completely useless for me now.
