It seems to be bad design that I can not just scroll down on the month view of Calendar, so that the grid just moves up. Going prev/next through the months is very uncomfortable any time you are dealing with periods of time that span from one month to the next!
Any method to get this function? Calendar/iCal has been around a while, they should have built this in — it is a common and convenient feature.

iCal is limited to the view modes you see in the main window - Day, Week, Month and Year. It's not very customizable.
However as an alternative, you might want to look at BusyCal. It's a pretty well regarded app. The two word pitch is "iCal Pro". It integrates with the system calendar, so all the built-in calendar based functions work fine, and in addition to iCloud sync, it has much better Google Calendar sync if that's a selling point. Most importantly for you it's more customizable in terms of views, and the month view scrolls by week.
Sorry there's nothing to be done with the existing app, but BusyCal is probably the best option to get what you want. There's a 30 day demo, so give it a try.
