Digital BW, The Print

Hi,

I've got an Epson 2200 and ImagePrint, and I'm getting excellent B/W 
prints.  I am fairly new to this and wanted to know if there is a 
preferred paper type (matte, rag, etc..) and brand (should I even 
consider using non-Epson papers ?) for B/W archival photos which 
will be framed under glass (are there alternatives here as well ?).  
I'm looking at print sizes ranging from 5 x 7 to 5 x 8.75 to 8 x 10.

Thanks for any info,
Brian
