If EAC got LAME from Audiograbber then I would have thought that you were using the DLL. I don't really know about such things though.
You can tell whether you are using the DLL or LAME.EXE by going into the Compression Options. If the first tab, "Waveform", is disabled then you are using the external compressor - in which case "Use external program for compression" will be checked on the "External Compression" tab.
If you are using an external compressor (advisable) then there are benefits to tagging via the command line. Check
the wiki for more info.
If you are using the DLL then go to the "ID3 Tag" tab in the Compression Options and set your preferences there.
I'm afraid I don't know whether iPods use ID3v1 or ID3v2 or either/both. I would try ID3v1.1 and additionally write ID3v2 (2.3.0) though.
