Hi mross,
1) Multiple pages will need to have video. Please suggest plug in to make handling this easiest.
I think Allvideos is the most flexible. You will need to combine it with a licensed copy of Jplayer for a commercial site.
2) What editor program do you suggest? Still JCE?
Yes. Still the best as far as I am concerned. I trust it and there are no surprises when they upgrade.
3. Any other plug ins or modules you'd suggest for a corporate site that will show products but will not be e-commerce because B2B big ticket type items.
Kind of depends on how extensive a catalog.
Using Joomla articles can work very well.
K2 would let you add some custom fields.
Something like Sobi Pro would let you make a very complex catalog with all kinds of editing capability and lots of refined search capability.
You can also use Virtuemart in catalog mode (no prices or ordering)
Hope those suggestions help. Everybody has their favorites. For me these choices have held up well over a wide variety of projects.
Cheers,
ed
