Silly question probably, but the jumpers I have are taller than the original factory one. But, the package is labeled SCSI jumpers.

I saw a couple of posts, but I'm still not clear -does it matter in the 7500 where the master is on the SCSI cable?>> --------- There is no "master" in SCSI. You can have up to 6 devices connected to a SCSI II bus. It does matter that each device has a unique ID set from #0-6. In your case convention is the SCSI controller on the logic board is #7, the factory setting of the CD-ROM is #3 and the factory setting of the startup drive #0. Thus case your second hard drive should have an ID set to either #2,#4,#5, or #6. --------- <<4. Should I just throw it all in and get a PCI card and install an IDE as a second drive?>> --------- Not necessary. However it will be faster than 10 MB/Sec speed of the 7500s internal SCSI bus.
