Can I get the installed software to crossover?

I finally succeeded in installing Win2k as a dual boot on drive D:.
It was quite a nerve-wrecking process because it seems to take forever
to finally ask me what partition to put it on, and I was thinking it
was eating Win98 the whole time. (of course I backed up first). But
it finally installed and both work. I do need to work on the wording
in the dual (selector) since it says Windows or Windows 2000 Pro.
It should say Windows 98, and I hope to add a Dos selection in there.
I'm assuming this is some batch file. So far I just got it installed,
that's all.

Now, one problem occurred. It insisted that it would not read the
file ir50_32.dll off the installer CD. It said to hit enter to try
again. I hit enter at least 20 times, finally hit the ESC key and it
proceeded. It does work, so I dont know what that was all about.

Now the question of the day. Is there any way to transfer some of my
common programs so they work on BOTH operating systems? These would
mostly be Agent, and Firefox, and a few picture editors. Or do I need
to install these twice?

I did use a FAT32 partition, so I can access all the files.

Thanks
