I am glad to learn that you are early planning for the upcoming Ratha-yatra festival. In this connection, I have requested the exact date of the festival from India but it has not yet been replied, so you may plan for any suitable date between 20 and 31 July—even if it does not correspond, we have to arrange conveniently, that is allowed.
So far additions for this years Rathayatra, you may make three Rathas, one for each of the Deities. The rest of the details are already there, simply you may may supply more money for festoons, decorations, flowers, bells, flags, etc. The Spiritual Sky is far away, but you just try to do it following Jagannatha Puri Rathayatra. Jagannatha Puri or wherever Rathayatra is performed is not different from the spiritual sky.
In the spring you may lead a very big procession on Lord Caitanya's birthday. This is a good plan to celebrate this great spring festival out of doors. So make this a very opulent procession with large Sankirtana Party and you may also celebrate in this way again with a procession on Janmastami day. These two important subjects may be observed in this way by all the three areas and similarly in other centers also.
Regarding your first question, a pure devotee is never under the modes of nature. In other words, no material laws apply on a devotee because he is fully under the direction of Krsna. So a devotee can continue his present occupation or he may change it if he likes. Krsna does not force a devotee because the devotee acts spontaneously according to the desire of the Lord; in this kind of loving service there is no question of force. Force is applied only when there is denial of Krsna. Just as the citizens of a state have freedom to follow the laws of the state, that is subordinate freedom, and the freedom of the living entities is also subordinate to Krsna. The clue is given there in the Bhagavad-gita that the living entities are fragmental parts and parcels of the Supreme Lord, this means that all the qualities of Krsna are therefore present in minute quantity in each of His parts and parcels.
