adding a more posts or list to category pages

[seventyone]

i've searched for this (as i am almost certain someone has addressed this issue) but to no avail

- the category summary page (blog template) is good but once the number of posts gets much larger than the default or what is a reasonable amount on a page (without scrolling forever) older posts get buried quickly
- we have a site that turns quickly so i'd like to insert a call that would list just the headlines of the other posts within that category and or link to an additional page that does the same at the bottom of the current page -- there is currently no pagination within this theme as that would also be an option, however, i tend to like the idea of recent posts being there in their entirety and the rest being just headlines
or
most of the newer themes use multiple pages (next page etc) and are more condensed in their listing (example new chrome) -- is that an easier or perhaps better long term fix (to implement that code)

if someone could assist with direction on this that would be great / thanks steve

i have been looking at updating Mag to Church (to be Rev2 friendly) but i has the same blog set-up
