You're going to kick yourself on this one <grin>:
<dtml-call "REQUEST.set('myseq', seq)">

Given your description, which I'm not sure I completely understand,
I'd suggest adding a Catalog to your site, and creating an index field
in the catalog that indexes your document sequence number. Also
make a meta data property in the catalog for the index field. To get
your complete list of documents, just call the catalog, and you'll
get back everything indexed. (If you index more stuff than your
documents, just query the Catalog for meta_type DTMLDocument, or
query your index field for >0 and <maxval.)
<dtml-in Catalog sort=indexfield>
do your processing
Take a look at the Catalog HowTo's to decide what stuff you want in
meta data fields and how to get the object given its Catalog pointer
if you decide you need to do that.
Hmm. To do prev and next buttons you could find the right document
by doing a search on your index field for a value less then the
current id (prev), sort in reverse, and do size=1 on the dtml-in.
For next, do >id and normal sort order and again size=1.
