Want to replace Indica wipers on my own - But How?

Hi All,
I am from Pune and I own Indica V2 DLS 2004 model.
I haven't changed wipers in last 2 years. So, this time I want to replace them.

Can you please guide me,
1. Which are the best wipers available for Indica V2?
2. What would be price of the wipers?
3. I heard that Bosch wipers are good, is it true? where will I get them in
Pune?
4. Can I replace them on my own or do I need to get that done from Service
center?
5. If I can replace them on my own; how to do that? Can you please share the
prodecure of the same?

Thanks and Waiting for reply,
