Answer 1

You are looking for the INDIRECT worksheet function:

=INDIRECT("SHEET2!A1")
=COUNTIFS(INDIRECT(A1 & "!$C:$C"); ">=" & $A7)

The function turns a string into a real cell reference.

Answer 2

INDIRECT does what you want. Note that if the sheet name has any spaces, you need to put single quotes round it, ie

=COUNTIFS(INDIRECT("'" & A1 & "'!$C:$C"); ">=" & $A7)
