As you were already told, the FFM requires special training and will not be usually easier than a normal setup. Of course, it has its advantages for some purposes, but probably it is not what you need.
When choosing the regulator, the first thing to look for is service availability in your area. Buying the best regulator available, which cannot be serviced by skilled technicians locally (and also in the scuba resorts you plan to visit) will not be the best situation for you.
I don't know about the specifics of India regarding this subject, but very-well known world brands, like Scubapro, Aqualung, Oceanic, Mares, Apeks and a few others should be safe choices. As you will most probably dive in warm waters 99% of the time, the usual reasons for chosing a cold-water regulator will not apply in your case (and for those 1% cases where you go diving in cold waters, you will be able to rent anyway), and this will decrease the price you will have to pay.
So.. the first step for your regulator choice research: what are the closest dive shops, how much do you trust them (from friends information, appearance, previous experiences, online reviews and any other means that you can judge) and what brands do they sell?
What brands have you used for the discover scuba dives and what did you found difficult about them exactly? (of course, part of the scuba experience that you will gain in the future will be regarding the operation your gear, but maybe there are some points that can be addressed by selecting the proper gear).
Regarding buying your gear now, it depends. The usual advice is to wait to get more experience before selecting anything, to avoid buying it again when you know what you really need. But this is not an absolute advice. Maybe in your case the scuba shops are too far away from the places you want to dive, too expensive to rent, not having well mantained equipment, not open when you need or anything else in this line, all good reasons for not wanting to depend on them and buying your own gear from the start.
