Amiga Supradrive hard drive questions

[max_lords]

Ok...I just got a Supradrive 500 XP hard drive for my Amiga 500.   It was in a package deal along with a big stack of game disks.   Unfortunately, I have NO clue how to install it and set it up!  it's a 105 MB hard drive w/512K of RAM.  I noticed that there's a slot on the right hand side of it that plugs directly into the Amiga.  When I do this, the drive powers up and spins but nothing happens.  

There are also several dip switches on it that I have no idea what to set to, and a small switch in the back that I also have no idea what it should be set at (an unlabeled metal one).  There are two ports in the back, one I THINK for a serial connection, and one for the external SupraDrive power supply that came with the drive.   If I plug the drive into the power supply and turn it on it also powers up and spins.  

So....how so I connect the drive?  Directly to the Amiga or with a serial cable?  Do I need the power supply or should I use the Amiga to power it?  Can anybody help me out?  I'd much appreciate it!  

Thanks!

Hmmmm...nope, those are the internal jumper settings for RAM, not the DIP switches on the drive.   And I still can't figure out the proper way to hook it up!

Ok...then here's my next question    

How would I download Amiga software with my PC?  I have NO clue how to transfer Amiga stuff from my PC to my Amiga.  I actually think I have the Supradrive disk here though...I'll have to check tomorrow cause all my disks are in the bedroom and my wife is asleep!  *sigh*

Well, I'm running Workbench 1.3 on my system, but I only have disks for Workbench 1.2, so I think I'm a BIT behind for the CrossDOS stuff!   I guess I need to score some updated OS disks from someone huh?

Or is the OS separate from my Workbench version?

So I need hardware ROMs to install as well as the actual OS?  Remember, I'm VERY new to Amiga stuff!  

And will my games still work well with OS 3.1?
