Back in mid 80's, Lonely Planets' best guidebook was their definitive 1 kg Indonesia Guidebook. It had everything you needed to know. I would strongly suggest you invest in hard copy and start flipping through it....might convince you to tag along.

When you actually arrive, there are a number of books at bookstores that provide very good information for expatriates (or google for them) .... my family relocated to Jkt for 3 yrs in early '90's and we found a couple of them required reading....can't think of the names off hand and know we gave them away already.

And don't forget to start getting your Hep A and B shots asap. This is not to scare you, just very good common sense if traveling internationally for first time.
