All your rogue class skills are still class skills when you go into Swashbuckler, they simply cost more points to advance. Able Learner reduces it back to 1, and lets you advance your rogue skills as per normal. You already have all the skill-monkey requirements by Rogue 3. Swashbuckler X gives you full BAB and d10 HD.
From there, just take battlefield control feats(stand still, Ex. Weapon Prof: Spiked Chain, etc) and you'll have a tank-monkey.
