I'm not sure exactly what you mean. I shoot RAW and tweak it in DPP, convert to JPG and resize to 800 x XXX, and upload to Photobucket.
So do I need to open the JPG an sharpen again in PSE before I upload?
Yes. I'd use USM at about 100, 0.6-8, 2 for that size, but there are a lot of setting combinations that would work.

And since you're using PhotoBucket, be aware that PB might resize again when you upload if you don't set the preferences to avoid that? From their support:
Before uploading your images to your Photobucket account, choose either a
display or file size that is equal to or larger than that of your images. You
can do this by clicking on the 'Uploading Options' link in your upload panel
and then on the radio button next to your preferred size. If an option is
grayed out, this means the option is not available for your Photobucket
account type. Selecting a size larger than your images will prevent further
resizing upon upload and help expedite the upload process. To make the changes
permanent, you must upload at least one image from the upload panel. This is
important for Pro users using FTP or anyone using the Windows XP Publisher. If
you choose to use the file size options, the file size of the original image
will take precedence over the the display size and any display size is
accepted as long as the file size is less than your choice in the 'Uploading
Options'.
I always click on the image to get the 100% size that I've uploaded, & then use that URL for display.
