1) There are no issues you'll run into. However, it appears this is your first time with tubulars. That being the case, I would take the wheels to a trusted shop to glue on the tires.
2) You can go with whatever size tire you want. What frame has issues running 700x23's?

and just a bit of unsolicited opinion - tubulars are completely unnecessary and overkill for a rec rider. The additional performance is not worth the $100+ per tire you're spending.
