P510 Accessories

A big hello to everyone here from India!

Been following this forum for a month now, and I can't thank you guys enough for all your posts, especially on P510. I placed an order for P510 this week and should get it by the next. To get the maximum out of it, I feel like getting a few accessories to go along with my P510. Can anyone suggest me to the right set of accessories I can look at? I might have a friend coming down from the US, so can ask him to make the purchase and bring it for me, but how much would the set weigh?

Thanks in advance!
