1) Last question first: If you are going to mail file, the W-2 along with 1099's that show Federal withholding are what must be attached. And NO, the TTX created "worksheets" cannot be sent in, only the Federal copies of the Originals from the provider.

2) No, of course not every stinking thing. Only the forms with an attachment sequence number in the upper rt corner (at least for the IRS forms....states might vary somewhat). BUT, if you make a selection to create a PDF and print a "Filing" copy...that copy will create a PDF of just the forms needed for filing on paper. (Could be a few extra sheets , but that could depend on each person's situation).
