How do I remove those grass clippings? Is hand picking an
option or should I use the blower/vac? Any advice would be
greatly appreciated.

I would mow the lawn twice when it gets that long, once north to south and then
east to west or south to north west to east your choice but I would go both
ways..... This way cutting up all those clumps adding organic material to the
ground. I always mulch my clippings, I've never bagged them.
