I "cut and paste" most of my references from different databases into Lyx, and numbering of my references is changing automatically within Lyx without invoking another program. That`s already quite comfortable. I don`t think that I will have much more than 150 references (and I already have about 120 in Lyx), so bibtex might be overkill.
no, bibtex is useful for > 5 references.
