Not sure about the other questions, but clusters are the "units" of the  mkv
container specification. There is a variable, but maximum limit to the size
(in bytes or duration) of a cluster. Once you pass a certain duration a new
cluster is started, it's normal. Look at the mkvmerge documentation for more
information. 
For ffmpeg specific mkv muxer options, they are listed in the fullhelp
