0ld wall recepter has four holes for phone line to plug into. can I buy a phone to match?

Any land line phone with a standard line plug or attached line should work just fine.

what side does the phone line plug in and what side to plug the fax line or does it matter two different numbers

The only one mattering is the one to the phone line. The others are your choice.

I have one wall jack, with two lines. Can I use this to have two phones plugged in, and have both phones receive both lines?

no only one phone line can use the jack not two different lines

will this work to run my wireless printer and my computer?

It works wonderfully with my home phone and printer/fax. Thus far I have not had any complaints.
