Do I really need the headset press adaptor or can I just flip the press cones to the flat side and be good to go, one cup at a time like the park tools website says?
No because the bearings a recessed to the cup and it might get damaged. Also you want to make sure it goes in straight.
I had to re-learn how to walk once, but never needed to re-learn how to ride a bike. Cyclist for life.
I think the CK piece for the head set press,
presses down on the bearing and the sharp finished edge of the frame insert,
I only have pulled and re installed a threaded CK headset.
On my 1 off touring bike (very long threaded steerer tube)
Given the OP is in Bike Shop saturated Portland, take the bike
to the shop with the proper tools and do it Right.

the ck press adapter press on the edge of the cups and centers the press
The CK bearing cartridges aren't removable so you can't install just the cups. I've installed CK headsets using a home made press with washers large enough to cover the outer edges of the cups and used a leather washer under each metal one to further protect the cup edges. It went in fine and worked with no problems.
