Ok, I'll admit, I couldn't resist giving my site a plug!
For those who don't know about them, I have a site up with downloadable Workbench packs aimed mainly at those with real Amiga's but they work in emulators too. You'll need a Workbench 3/3.1 adf in order to get them booting. Oh, and a kickstart file too. Apart from that, they're something for nothing which can't be bad eh?
There is even a stand alone pack for A600/500+ Workbench 2 users!
Full instructions are provided on the site, along with screenshots and a video under "Features" in order to help you decide if they're useful or crapola.

The video is also on YouTube, the site that attracts the biggest piles of digital junk the world has ever seen!

Don't be scared now, have a peek. It's measuring like 99.98% on the geek factor scale so you may have to take a shower to remove its lingering geeky-ness after you've viewed. You have been warned.
