About the floppy drive: check the Sony label on the drive. If it's black you've got an 800K drive. Blue labels identify high density drives (sometimes called SuperDrives or FDHD drives). The number you are reading, if I recall, is the number of the bracket part and not the drive itself.
If you need a new 800K drive PM me; I have a few I could offer.
Now, as for the hard drive: Try running Apple HD SC Setup to see if the drive is recognizable (provided the drive is an Apple-branded one). It should be on your System Tools disk. If the drive is non-Apple you'll need a utility like Silverlining to format it. Also, don't forget to check your connections between the drive and logic board inside the Mac. If you have an LC or other easy-to-access Mac sitting around you might want to test the drive inside of it just to verify that it is working.
The error code: A "3" as the eight number in the top row signifies that the problem is located in RAM bank B. Try swapping your SIMMs with known working ones (if the SIMMs in the working SE are identical try swapping them).
Your code isn't an "illegal instruction" because there is no "F" in the code. If there is an "F" it is always software-related, which an illegal instruction would be (the non-F codes are hardware-related, which is your SE's problem).
