We routinely use the boiling lysozyme method.  Prior to
sequencing, we RNase treat the sample and then Strataclean (we
used phenol previoulsy, but the Strataclean resin is just as
good and reduces organic disposal).  The only problem I would
see is your use of pBR322.  My experience is that pBR322
plasmids just give very low yields of plasmid relative to pUC
or pBS.  We have had very good success with cycle sequencing.
If you have that capability I would try that.
