Looking on women is not an impediment to spiritual progress, but looking on women with a view of sense gratification is detrimental. The actual fact is that attachment for sense gratification is not at all congenial for spiritual progress. In this country intermingling with women is very easy, and sometimes our mind becomes agitated. Therefore we have to take little precaution and the best precaution is to raise oneself in Krsna Consciousness. Lord Caitanya said that His mind becomes agitated even by seeing a wooden model. By seeing women, if one's mind is agitated, that is quite natural. If you take the words of Lord Caitanya that His mind is agitated by seeing a wooden model, then what to speak of us by seeing actual women.
The real fact is therefore that we have to check ourself by advancement of Krishna Consciousness. But if it becomes too difficult for us, then one should get himself married and thus check his sex disturbance, and peacefully prosecute Krishna Consciousness. But if one can avoid sex life and the attachment is overturned for Krishna Consciousness, his position is very laudable. So there is no need of becoming hypocritical; better one can get himself married and be peaceful.
To make noise in front of the Deity means talking nonsense or indulging in useless topics of conversation. Chanting of Hare Krsna mantra is never prohibited. In the Nectar of Devotion you will find all these prohibitions and try to follow them.
Yes, if you live in India it will be better facility that you have some preliminary knowledge of the local language. This was recommended even for big British officers who used to go to India either for business or for political purposes. I was a student in the Scottish Churches College and 90% of our professors were Europeans. All of them learned Bengali just to understand the local language. Although all of them were speaking with us in English, still they could understand Bengali nicely. Acyutananda has already learned Bengali, so I think for preliminary knowledge in Bengali there will be no difficulty for you.
