Some pad dont have the groove in the middle, but if your pads did, the one of the left would have 1-2mm left untill it hit the bottom of the grouve. I would buy a new set and have them ready when you have dry day to swap the pads at that point.
Btw the reason the left is worn more than the right, is before the piston on the right need cleaning. Pump them out, then spray with brake clean and clean with old tooth brush and length of string/twine for the hard to reach gap betweewn the piston and the caliper body. Once they are fully clean you should be able to push them back with the fingers/thumbs, pump them out, clean push back a few times untill the movement is easy to do with your fingers.
Down the road you may need to do a full service one them, so thats a thin peice of wood/plastic (the same width as the cap in the caliper) in the middle of the caliper and pump the pistons untill they meet the wood/plastic. Do this on both calipers, then remove then you should be able to rock/push the pistons with your thumbs till then pop/come out. That last bit you may want to do with the calipers removed from the bike, and of course have old tshirts/towels hand to protect the wheel/fairing/mudguard from brake fluid. I have a small thin flat blade jewelers screwdriver that I bent at 45 degrees so help me scrape the crap out of the seal grooves. If you can get a good deal on them try and go oem on the replacement dust/brake seals, but any make od DOT4 brake fluid will do.
