I moved your post over to the Casual forum, as this is a casual game.
What you do/don't do about the obstacles depends upon the level.
I can't find any YouTube videos specific to the level you are on, but maybe looking at the second set of levels here would show you something similar that would be useful.
This "original" version of Jewel Quest is one I have always permanently kept on my computers.
There ARE boards where some things can't be moved. They're there specifically to make you work around them and to make the level more challenging.
Is this the first time you've played the original Jewel Quest ?? I found the game pretty difficult the first time I played it and still have to re-play boards now and then
