Yes, joeytay, there are many options you may start looking. But again, with the cities that you want to go to, the Oneworld alliance may not be of service to you, and you might be better off trying one of the other alliances.

CAI is no longer that cheap anymore.. and besides you didn't say if you want F or J class travel.

Still you're bouncing around Europe too much. Best for you to do all your European sidetrips first (especially the short ones), and then concentrate on the longer routes for the long-haul carriers.

Read on the sticky, plan your routes, then post here for questions AFTER you plan on your destinations/cities. Otherwise use the services of a travel agent who will galdly plan everything out for you.
