I have experimented with many keyboards and I've found the wireless Microsoft Comfort 5000 excellent along with its respective wireless mouse.  Regarding monitors bigger is not necessarly better it really depends on a number of factors such as the screen resolution, the bezel edge size, and blue light emmisions. I've found the Dell U2515H 2560x1440 very good, I have two and may buy another. 24 inch seems to be a sweet spot for coding and althought I initially thought the low blue light emmissions was a marketing gimmick it's definitially less tiring on the eyes over long periods. Most monitors seem to be 1080 depth nowdays but 1440px saves a lot of scrolling. I have more or less the same setup at home and work. One other thing, I'm always amazed how employers tend to only supply one monitor to their workers when its such a cheap way to facilitate productivity?.
