Decipher Script, Speak Language, and Spellcraft would make sense as books. Spellcraft might also work as a large collection of scratch'n'sniff stickers for matching material components.
Bluff, Diplomacy, and Gather Information checks vary quite a bit depending on the circumstances, but you might could argue that a masterwork disguise kit could help you project an "honest face" or "repays favors and remembers insults". Intimidate could be similar, or could be shoulderpads and assorted accoutrements to make you look bigger (larger creatures get a +4 to Intimidate per size category); giant shoulder spikes encrusted with the dried blood of your enemies would also work in some circumstances, though there might be some diplomatic consequences. Sense Motive might be a flashy coin or some other minor distraction used to get someone to lower their guard momentarily in surprise.
Handle Animal should likely be handled like Craft - when the only tool you have is a goad, everything starts to look like an elephant.
Truespeak could be a special helmet that blocks out distracting sounds and conducts your syllables so you can hear yourself better and adjust the pronunciation minutely where indicated; or a glass of water, backwards forwards anagrammatized.
A Survival kit could include pressed leaves for species identification, but should also include a knife that is shaped just so, bits of string, a shovel, and a spritzer of owlbear urine.
Sleight of Hand - gloves that are slick on the outside, rough on the fingertips, and bear cleverly concealed hidden pouches.
Balance could be boots with nice grippy treads; probably not compatible with masterwork boots of moving silently.
A book of Jump would definitely include inspirational tales of the exploits of Spring-heeled Jack (
