Yes, you'll need two I-140's and two I-485's with two sets of fees and medicals. But it might be better to file both I-140's with just one I-485 (for your employer) to reduce your expense and USCIS confusion. Then watch and see how your employer's case is going; if it's not going well, file the I-485 for your NIW I-140.If you apply for I 140 NIW and I 140 employment based are you supposed to send two separate I 485 with two different medical visit forms?
