Squirrel condom is slang that is used on this board for the little rubber boots that fit over the vacuum ports. It's good to keep spares handy.
As for the jets, I recommend that you use Pat's jet calculator to determine the size that is best for your set-up. His website is
www.dinqua.com or you can find it in the tech vault. 130 mains may be a tad large for one baffle removed on the stock pipe. However, if you intend to keep removing baffles and pull the snorkel they may be fine. 42 pilots should be stock, shouldn't need to change them.
