I agree, trash the hold down piece, both top and bottom. The bottom one is some kind of safety thing.
Then remove the diaphragm for the vacuum from the bottom of the table, it tends to get clogged if you use it.
I too loved the goose neck LED light on the Porter Cable saw, and I still am sorely disappointed in the high dollar saws that think that less than $5 per unit is prohibitive.
I put the air tube on the right side like you are talking about, but I just looped it around and changed out the nozzle end too.
Put a magnetic sheet on the table top, even if it does not stick as it should, use double sided tape to hold it down. Slicker than owl sh*t and no waxing to worry about - pic attached.
