Lot of good ideas/suggestions here. There are lot of Indian doing very well in IT  and I have seen some of our guys getting into this field slowly. All it takes is your firm dedication and willingness to put few months on core programing/training. If you can find a consulting company, ( sulekha.com) it does not really matter where u can go and train, as most of them provide you with free housing and training. If you make it successfully, they will take cuts off from your salary and  in most cases place you on the job and sponsor for your H1B. I think this is probably a good way to go for most college graduates on OPT that are having hard time to find a job based on their major.

As for technologies to train, it depends on your background/interest. You can can train in any programming like java,.Net, C++,  database programming or if you dont have any tech. background, may start out as QA/BA and learn more as you go. If you have good technical/business background then one can try learning ERP programming like SAP or Oracle but the efort to learn these may take longer.
Do some research, call consultantancies and see if there in an training offer you like. The opportunities in IT is better than most other fields.
