Tips for Experiencing Indonesia?

Going to be heading to Indonesia for about 3 weeks in late August/Early September (I know I'm planning this way in advance, but its exciting!). I'd be interested in any advice people have, first for travel during Ramadan (I might catch the end of it) and second just for any must see things or ideas that are more off the beaten path. Any advice, suggestions, or experiences would be greatly appreciated.

P.s. It doesn't have to be photo related I'm just looking for other people's ideas and experiences on the best way to experience the country.

Thanks in Advance,
Chris
