To order certificates, do so through the General Register Office (GRO):
http://www.gro.gov.uk/gro/content/certificates/default.aspThe cost is £9.25 per certificate.
You will need Year, Quarter, District, Volume no, and Page no.
The film numbers you have are FHL Film Numbers, and relate (I think) to films held by the Church of Jesus Christ of Latter Day Saints, aka Mormons.
You can order these films at your local LDS church, for viewing there.
Alternatively, look them up on FamilySearch?
