Trying to be succinct

I need to transfer about 150 VHS tapes to the digital world. I might not ever burn them to a disk rather store them and play them from a HDD via WD TV.
Assuming I have a high end JVC deck, from the research I have done I was planning on going
VHS>a Full TBC Unit->Proc AMP-> Computer

Then I was told I should purchase some type of software to remaster the video

Then I was told I should just do:
VHS->to Capture Card>Computer and the Capture Card would allow me to remaster the video.

OK, What should I do? What is a good quality but good value capture card for a Mac?
DO I need a TBC?
DO I need a Proc AMP?

Thank you all in advance for your help.
