I'm a big fan of friction--but have noticed that you can often find quite
good deals on 8 speed bar-ends on e-bay, seeing as a lot of folks are
moving to 9 and 10 speed clusters. you'll need a new derailleur as well--a
brand new Shimano 105 will shift great and set you back a whopping $30.

Or you could just friction shift...

Not in particular. You should probably replace the chain when you
replace the cassette, just as a matter of course. Double-check the
spacing of your rear triangle- if it's 126mm, you may have trouble
fitting the Aerospoke rear wheel. See

Yes, but the same is true of 9. 8-speed is a bit of a dead end, and I
would advise against it.

You don't need to change that much stuff.

To convert to 9-speed friction, all you need is the new rear wheel with
a 9-speed cassette and suitable chain. (You should always replace the
chain when you install a new cassette.)

If you want go to with indexing, you'll also need to replace the shifters.

The 9-speed Dura-Ace bar-end shifters had been in very short supply, but
we just received a large shipment of them.

You don't need to replace derailers or chainrings, the ones you have
will work fine.
