Is 3GS (old bootrom) able to unlock (using 6.15.00/ultrasn0w) on iOS5? Or should I downgrade to 4.3.5 (saved SHSH) first?
 
I even included the correct link to one that's not out of date.

You added the link later, and it does not address my issue. The phone is already on iOS5. I don't need to preserve baseband.

I want to know from someone who has already done this, if I can use the ipad baseband with iOS5.

I don't think you're going to find a lot of people "who have already done this", as combination of iPhone 3GS / old bootrom + iPad baseband 6.15.00 + IOS 5 is a rather unusual one.

Assuming you have a functional JB'ed phone with 6.15.00 - just run ultrasn0w and see what happens. Ultrasn0w supports 6.15.00 baseband, so in theory this should work.
 
My 3GS is exactly this combination. I downloaded a custom 5.0 ipsw that preerves the baseband after I upgraded to the ipad baseband. Ill post the url link I used to upload the custom rom that preserves baseband when I get home from work.

Try sticking with 4.1 and then download the custom ipsw i downloaded from the link i posted above. I used redsn0w btw
