I've not followed this thread from the beginning  but it is  
definitely possible to record a source with plugin effects in place.

Firstly you have to set up input audio objects in Logic that  
correspond to your audio interfaces physical audio inputs. Many do  
not even realise there is such a thing as an audio input object.

Then say you're recording into input 2 of you audio interface, then  
you would insert Guitar Amp (or any plugin) on "audio input object  
#2" inside Logic. Then on the track you're recording onto, select  
input 2 as source and you will record the sound you are hearing.

Depending on the plugin used the latency may be acceptable or  
impossible to perform with.

This is completly not necessary. Do it how I describe above.

Yes, and you will not record the sound set this way. You will only  
monitor it. As mentioned above record FX inserted on an input object  
will incur the same amount of latency as well. Try dropping your  
audio buffer size if you haven't already. The 2882 has fine drivers  
and should be able to cope with a 128 sample setting - offering about  
3 - 6 ms of latency which is generally regarded as the highest amount  
of latency most people are prepared to accept during live performance.

Logic's Guitar Amp Pro adds very little latency and I often get  
guitar players to record through it. Bear in mind that if you are  
running other plugins and virtual instruments inside the same session  
they will add to your overall latency as well if plugin delay  
compensation is turned on - which it should be - as to leave it off  
will fix your latency but you have no assurance that all your tracks  
will be in time together

No. You can't assign a bus as an input to a track in Logic. There is  
a workaround though. Using any plugin that has a side chain input,  
insert on the track you want to record onto. You can select a bus as  
input there and then record it back that way. I've not done it myself  
as I use a RME interface which allows me to patch an output back to  
an input digitally so I get around it that way. Probably the 2882 can  
do this also.
