To start with, use the 39t inner ring in the outer position, you might want to get a bigger ring later but for now you can save your money.
48/19 falls about halfway between 39/15 and 39/16, so I'd start with both those sprockets and see how you get on. Using 8/9-speed chain on 10/11-speed chainrings is no problem, but 10-speed chain probably won't work on single sprockets, unless you've broken them out from a 10-speed cassette.
The wide-base comment is valid, but as the Hope Trials hub has a steel cassette rotor it's less of an issue than it would be if you chose a weight-weenie hub with an aluminium rotor.
