Ubuntu :: HDD Partition Setup For Triple Boot?

I've looked everywhere for a satisfactory answer, to no avail. I wish to triple boot xp/98/ubuntu 10.10. Is this an appropriate HDD setup? (it looks like this in partition magic pro srever 8.05)

*:SYSTEM........ NTFS......... primary ..........(for xp)
C:WIN98......... fat32 .........primary,active (for win98 )
*:UBUNTU....... LinuxExt3 ...Primary ..........(for Maverick Meerkat)
.........* Extended
............. *:SWAPSPACE2.... Linux swap .....logical
. ...........D: DATA................. fat32............. logical (for all things backup)

There is nothing on any of the drives at this point. (I am submitting this on a crappy 233mhz win95 laptop)

Here's the information i've gathered so far... Install in the following order: 98, XP, Ubuntu XP's drive label MUST be "SYSTEM" (I think?) Installing multiple os's is easy (i've read) if you hide unused partitions during install (ie. if installing XP, hide C:WIN98 and *:UBUNTU partitions) but i can only do this with FAT formats, and if i do that, the dirve letter changes, which is a problem (i suppose i could manually hide/unhide, and set active the partition I want at every boot-up....(Damn))

And here's a couple more questions SHOULD I make everything fat32? do they have to be primary to boot? ('98 on an inactive partition won't load) Once they are all installed... where do i put grub? Do i put it in first? Also, I deleted my dell utility partition to do this, is that a problem? (LOL, I have NO idea what I'm doing...Fck)

Like i said, finding information about the partition setup (logical/primary) is damn near impossible. Even if it's just a "Ya that'll do for a setup"

I'm gonna keep experimenting, since there's no longer anything to lose on my HDD, and i'll report back any improvements I come across
