Yes, the patent is still active. Google patents indicates that the expected expiration date is April 5th, 2029. This is later than 20 year from the priority date so there likely has been a patent term adjustment. I checked on the US Public Pair site and there seems to be 629 days of patent term adjustments. This can occur when there are delays in processing the patent application.
As for the similarity between the patents, the earlier patent was cited in the later one so the examiner clearly knew of it. I'd review the patent's file on the US Public Pair to understand how and why US 7,927,287 was deemed patentable.
