2.3.3.2 is already a newer version than 2.3.1.7, so any improvements in 2.3.1.7 are already included in 2.3.3.2
It is not possible to upgrade modules individually, if you want to upgrade to a newer version of mojoPortal you get all the newest versions of all features.
As far as source code, we no longer support use of VS 2008. The free Visual Web Developer 2010 can be used with the latest mojoPortal source code.
I have no idea what you mean about html recycle plugin, we have no such feature.
Hope it helps,
Joe
