Thinking of starting a W554 set

[x2drich2000]

Good afternoon,

I'm currently considering starting another set and the W554 set caught my attention. However, I am not familiar with this set and was hoping I could get some more information regarding this issue. Due to budget constraints, I imagine I would be looking at VG or lower condition. Below are some of the questions I have, but please feel free to add any additional info you may have.

What is the card stock?
Are they condition sensitive?
Any common condition issues?
What is the difference between the B&W and browntone? Are all cards found in both versions? Any premium on either version?
From the checklist it seems Ruth & Gehrig are the two big cards. What is the general fair market value of these two in VG? How about commons?
How difficult are the cards to locate via Ebay or major shows like Philly?
Any individuals that are more scarce than others?

I know that is a lot of questions, just trying to get a better idea of the set and see if it’s actually something to consider pursuing further.

Thanks
