Conjugation in Alkadienes & Allyic Systems

What are the differences between vinylic & allylic hydrogens in a Cyclohexene (ie. how many of each, what determines it)?

Second, what is the best way to determine a conjugated diene? Are there any rules?

In 1,1-dimethylallyl the cation is positive: which type of carbon is that, tertiary?

In 1,3-butadiene is the activation Energy around the C-C central bond about 4 kcal/mol?

In the Diels-Alder reaction between 1,3-butadiene and ethene would the product be 1,4-hexadiene?
