Hey there...
Filter socks are mainly used in the inlet section of the sump. The idea behind this is filter out any large waste particles coming from the display tank down in to the sump..People also put bags of nutrient removal media in there like phosphate removal...
Yes, the fuge or refugium, contains the dsb, live rock rubble and the macro agae..
The bubble trap is simply 3 parts of glass or acrylic, staggered in height, as in the attached picture below...
Water will flow through the above, say right to left...over the lower pain of glass, under the middle and then over the last one and into the return area..The idea being that bubbles will get trapped here and not end up in the return section and go back to the display tank...
In the return section, there is simply your return water pump, submerged usually. This, obviously takes the water that flows through the entire sump and sends it back up the pipe work to the main tank...
Have a view on this page from Melev's Reef which will expalin all the basic concepts of how sumps work and basic designs..

One thing to remember with sumps is that there are many many ways to configure a sump, they all work in their given setup and how they are configured is also down to personal preference...
Hope this helps a little...If not, just shout up with any more questions
