This video and tips are for the mobile/tablet version of Level 42 (see below for the 8 moves, 2 cheeses version)
Try to make large words to clear the vines with line blasters, but also don't forget how useful 4 letter words and crowns can be to help you clear the board.
Vertical line blasters are great for dropping the cheese quickly.
Also crowns will clear vines and tiles from under the cheeses for you!
Computer version
To pass this version with only 8 moves you'll need to concentrate on only two columns to get the cheese down.
Making long words that end in vertical line blasters works well.
Or just clear the vines, then the letters from only under two cheese.
