First question (Q2.) has been solved here. please post other question separately.
The reaction is formation of alkene from alcohol. H+ from the acid protonates the alchol groip and water ( a neutral group) leaves, forming secondary carbocation. This carbocation rearranges to tertiary carbocation (which is more stable) and than elimination occurs from this carbocation to form alkene. Note that 2 alkenes will be formed and the more substituted alkene (the product as shown) will be the major product. This is according to Zaitsev's rule.
See below for the mechanism.
(Note that numbering the ring is for explaining the connectivities of bond before and after the rearrangement. It is not according to IUPAC numbering conventions. )
