Well, considering that Shimano (and, others) says that you should only use the connector pin on the 9-speed chains (was the same true for their 8-speed chains, too?), and I stopped using the connector pins after the FIRST time I used a 9-speed connector pin, you may-or-may-not be able to just use an existing 10-speed chain rivet IF it is still in place.
Otherwise, you will typically need TWO connector pins ...
As far as using two, joined links vs. two separate outer plates ... I just don't think my dexterity is as high as it was when I was younger and so I just think it would be easier for me to install two joined links rather than separate plates ... that's just me -- I never recommend a methodology I wouldn't employ.
