I play in the woods and paintball pants with built in knee to shin pads do everything I need for shin protection.
For knee pads, PE makes and great set, really cushioned. The issue I have with them are the Velcro straps. Like most paintball knee pads, if they are not tightened perfectly they will rub you raw.
Volleyball knee pads are about as cushioned as paintball ones, and on the plus side are spandex and 1/2 the price.
Compression with individual hex pads (McDavid) are extremely comfortable but do not have as much cushion as the two above. You will be a little sore at the end of the day with your play style.
