I'll be keeping my eyes on Shahbaz Nadeem, the Jharkhand skipper. Haven't seen him bowl enough but telling only from limited experience, he can develop into a good test match bowler if nurtured well.
As for the Ashwin/Ojha duo, I'm glad that people now realise how Ojha is a more reliable option of the two. Ashwin bullying WI and NZ batsmen at home had made people think of Ojha as sort of secondary, or a more run-containing defensive bowler. Ashwin needs to concentrate more on his stock delivery rather than his carrom-balls and other variations. In test match cricket, you'll have to think proactively what the batsman has in mind. And currently, Ashwin doesn't seem to be doing that well enough. He's very inaccurate with his lengths too.
