While six procedures are required of the 2000/2008, this does not mean that six separate documents are required. "Documented procedures" means that it is documented in QMS procedures somewhere.
In 1994, many thought that 20 procedures were required of the standard. This was not true, in fact it illustrates an element-by-element approach--which is a bad idea from the perspective of quality assurance.
Now that the 2000/2008 standard explicitly requires six procedures, many think that six is the clever/magic number of procedures. Same mistake.
The number of procedures depends upon how many processes are in operation that impact quality. Don't confuse activities with processes here, and you'll be okay. (Focus on major processes--processes at their highest level, maybe.)
A procedure simply describes how a process is carried out. If you have a process, you have a procedure. The standard does not, and never has, identified companies' "quality system processes" (with the exception of the required support processes). So the number of procedures (beyond the required six) depends on the organization--not upon the standard.
Don't write procedures to address the requirements you sited, write procedures to describe the processes. Then review them to make sure that conformity to the sited requirements is clear, as applicable.
