Help needed with the Portfolio

Greetings! So, we're working on adding portfolios to the site. At this point, I'm not sure if we should be using a portfolio vs a gallery, but this is what we're doing: 1) We have *disabled* the Portfolio in the theme options. This means the portfolio won't appear on any site page, automatically. 2) We have manually created some projects in the 'Portfolio' section. We have three projects created and when I view the "Portfolio" page (i.e. www.{mysite}.com/portfolio/) I see the featured images for my projects and links to each portfolio. The links work and the featured images appear just fine 3) When we view an individual portfolio, the content appears as expected. My questions: 1) When viewing the "Portfolio" page, the page header reads "ARCHIVES: PROJECTS". That text appears in a <div> with "section-title" as a class. Below that, the text "Portfolio Items" appears. Is there any way to control the text that appears at the top of the "Portfolio" page? 2) Is there any way to control the order in which the portfolio items appear on the "Portfolio" page? 3) Are we using portfolios correctly? Should we be creating galleries instead? Thanks in advance!
