It's not "bonus dice", but an actual increase to the Reaction Attribute. So yes, it applies to dodge, piloting, etc.
Are you sure about that? The book says, "This power increases the speed at which you react, just like wired reflexes. For each level, you receive
+1 die to Reaction (this also affects Initiative) and 1 extra Initiative Pass. The maximum rating of Improved Reflexes is 3, and the increase cannot be combined with technological or other magical increases to Initiative." Note the bold text. That's +1 die, not +1 to the Reaction attribute.

The reason that skills have a "default" linked attribute is that there's typical one attribute that's used nearly all of the tests that skill is rolled for. In the rare cases where a different attribute is used for a special "unique situation" test (such as a Software + Stamina test to see if you can stay awake 96 hours straight working on that coding project that simply can not wait for sleep), bonus dice to the skill's default attribute don't carry over, simply for the reason that that attribute is not being used in the test. Bonus dice to the attribute that is being used in the test will apply however.
Alrighty, that's pretty much what I was thinking. With this in mind, if you have Tailored Pheremomes rating 3, what bonus do you get with the Negotiation skill? "Tailored pheromones add their rating as a dice pool modifier to Charisma and Social Skill Tests" (SR4, 339). Tailored pheremomes at rating 3 are adding 3 dice to Charisma tests, and 3 dice to Social Skill Tests--which incidentally all use Charisma as their linked attribute. So, do you get a total of a +6 bonus (+3 due to the bonus to Charisma, and +3 due to the bonus to Social Skill Tests), or +3 (only the +3 to Social Skill Tests)?
