That sounds like a good plan.
If you have anymore problems you know where to finds us all.

One more question:

I'm using PartitionMagic to form the partitions before I install. Should I make the Linux partition an active partition or a secondary partition?

Both types will work, from my experience it is only windows that argues with that.

If you want to leave room to play with other OS's a safe minimum of 6gb for / will do for slackware. The size for your swap is up to you, but in general a safe option of 1gb for up to 1gb of ram and anything over 1gb of ram does not really require any swap, this will do for a general use workstation. But swap size is a whole different topic and there are many different views on it, look around on the web and on this site for the different opinions

I'll try it as non-active for now, and if worst comes to worst, I can change it later.

BTW, I deicided on 5 GB for Slackware with a 500 MB Swap File (Although I have 1 GB RAM)

Is it safe to make Slackware the active partition, because it still isn't booting to it. My program for partitioning tells me that only the active partition is bootable...

It is safe to make it an active partition.

Before you do that try and boot using the install disc like I described before.

When you installed slack where did you tell it to put lilo. In the mbr, floppy or boot

I told it to be in boot... should I have put it anywhere else?

That depends if you are using any other boot loader. If you where just booting windows normally (ie you turn the computer on and it starts windows) and now you have added linux you should put lilo in the mbr. Then when you start your computer you will get presented with the lilo prompt and a choice of what OS to boot. As long as lilo was configured correctly.

OK... so I try to boot it off Disk 1 into hda3, then I run liloconfig and redo it, this time in the MBR. Got it!
