There are 11 recalls on the 2007 Camry. I suggest you contact either Toyota or a dealer, give them your VIN, and see if any of them were done. Were the people you bought the car from the original owners? If not, Toyota may not have known their address, and may not have sent them recall notices. Anyway, your problems are not a month the 11. Some seem serious, like the air bag recall. You should find out ASAP if any recall fixes were made.
As for the sticky dash, you could replace it or put a cover on it. A cover is a lot less expensive. A cover could be a fabric, or maybe a wrap. See if any shops wrap cars in your area. Call one and ask if the would wrap your dash. Off beat idea, but someone might do it. Do a web search for dashboard covers and see if anything appeals to you. The visor can be replaced with a used one from a junk yard. Check around and see if a junk yard near you has any. You might also find them on line, but you can’t see them before you buy them on line.
