A couple things. That's a contractor saw, not a cabinet saw. No amount of side table/outfeed/fencing system will ever make it into a cabinet saw. Cabinet saws are 1k+ for a reason. They are built with die-cast metal to be heavy as hell and are belt driven monsters. They can rip 8x4 sheet goods and not even tip slightly. I had that same Ryobi and I used it for 8 years and it served me well. I did however notice a crazy difference once I got my hybrid saw. With that Ryobi you will have to "Push" wood through, which makes it dangerous. Get a new blade right away, Freud Diablo are nice blades readily available and moderately cheap. Also, put your guard back on period. That saw doesn't come with a riving knife, which is crazy stupid, so that guard is the ONLY defense you have against kickback. It's not as great as a riving knife but it's better than nothing.
I'm sorry if the above comes across as me being a jerk but I'm concerned for your safety. Unless you're this old house good, that table saw is a dangerous purchase.
