Hello ! I am glad I am not the only one dealing with such a common problem in the writting of scientific paper. 

Well, let me tell you how I am writting my PhD thesis and deal with the bibliography problem. I have decided that my reference would appear as 'Johnson M, (1956)' say. So the problem is different from your however. 
I have a program that handle all my references which is called Procite which I would recommend to anybody writting up book, thesis. I can add up references at any time and Procite will re-arrange them in alphabetical. The output can be customised so it can appear as [1] Johnson M, (1956), or Johnson M, (1956). 
The output file of Procite is then imported in Framemaker with the RTF filter. The reference can be simply copied to a bibliography file from framemaker. However it is important to format the bit of the reference that you want to appear in your Xref as a different format from the rest of the reference. For the bit that will appear in the xref you will need to use Runin Head in pagination under paragraph designer. 
This way you can create a xref in your text and it appears the way you want [1] Johnson M, (1956) or simply Johnson M, (1956). When adding a new reference re-use the program Procite and re-insert from the new RTF file in the Framemaker bibliography file. This way you can handle Alphabetical bibliography and inserting new author is not a problem. 
Now, this work well for alphabetical however if you don't want alphabetical (unusual) there is not much I can think of now. Your problem is not so much the alphabetical order or not, it is the numbering problem. If the reference are numbered, then any author you are going to insert is goign to mess up your numbering list.  
I would suggest: 
1) Use the technique that I have mentioned above and for the draft of your thesis insert the author name as well as the number so the xref appears like [1 Johnson M]. 
2) After you finish your draft generate the list of xref reference 'say' and re classify them in the order they appear on the generated list. 
3) Re arrange your bibliography list the way it is done in the xref generated list. 

If you were using alphabetical there woul be no problem. I am a bit like I had reference there and there at any time. 

Please do not hesitate to contact me if you want me to send you an example of my template.
