First thing - don't depend on the PR you see in the toolbar when you're assessing the results of a recent change to your site. Google has not exported PR data to the toolbar in almost 5 months.
Last week the site www.example.com/ was indexed but not www.example.com/index.htm
This would be the normal, healthy situation.
...currently even www.example.com/ is not being indexed by Google.
Now I'm confused a bit. Do you mean the domain root is not being spidered? Or do you mean it's no longer in the results when you use the site: operator query? The first situation would not be too big a concern as long as it doesn't last too long. The second would be a major concern - unless the domain is showing up nicely for regular searches and bringing you the level of traffic you got previously. In that case, it's most likely a Google reporting bug.
...should we redirect www.example.com/index.html to www.example.com. Is it really compulsory to do that.
The concern is that Google may split PageRank between what is, technically, two different URLs - instead of seeing just one "page" and letting all PageRank accumulate in one place. This was a problem a while back, but lately I'm not running into it. Still, it is a safeguard to 1) never use index.html in your internal linking 2) put the redirect in place.

Currently the domain root www.example.com/ is not getting spidered. It was earlier getting spidered. When you type cache:www.example.com/ all the rest of the pages are coming up that are spidered except the home page. Also many pages are spidered and some are not spidered including the Home Page too
As the previous poster commented, the PR toolbar update hasn't happened for a while, so don't worry if you don't see PR on the toolbar for your interior pages - if your previous url's are properly redirected then the new pages should be getting the benefit.
