Can anyone recommend a good AVR book...

I think you're right. ATmega8. For about the price of a Six Dollar
Burger at Carl's.

Also strongly recommend that you consider getting Atmel's AVRISP
programmer. When you're just starting out there are SO many things that
could go wrong it's comforting to have confidence that the programmer
and its driver (AVR Studio) are off-the-shelf parts and are blessed by
the manufacturer, and so therefore slightly less likely to be the source
of whichever problem is occurring.

For example, new ATmega8 chips come from the factory set to use the
internal RC oscillator. Odds are pretty good that you'll forget to burn
the fuse that switches the clock to use an external crystal or clock
generator [not that *I* have EVER forgotten to do that <grumble>] and
end up with a chip that kinda-sorta works but that won't talk to the PC.
Lots of other things can go wrong that cause similar symptoms. Do
yourself a favor and start off with one fewer ...

If you meant Carl's... Carl's Jr. Hamburger joint. Burgers start at
about $3.99 (at least in California).

If you meant the chip...

Digikey: ATMEGA8-16PC: $3.66
Jameco: ATMEGA8-16PI: $5.05 (ok, maybe that's a burger with fries and
the Coke :)

Read the forum at avrfreaks.net for an hour. There is an online book at
smileymicros.com that describes using the winavr gcc c compiler (free!)
and the atmel butterfly eval board (about $20)

Must be a regional chain. None around here.

And what's the difference, anyway, between the AVR and the ATxxxxxxxx
series of chips?

AVR is a subset of the AT- series

(AT- indicates ATMEL, AVR is some of their products)

AT90- ATTiny- and ATMega- are the AVR parts,

Bye.

The latest version of Atmel's AVR development environment works
together with winavr. This means that you can write a C program and
single-step it in the simulator, watching register, memory and i/o port
values.
One thing to watch out for if you use a serial in-circuit programmer -
it is easy to lock yourself out of the device by setting the fuses
incorrectly.
In particular, setting the watchdog timer to "continuous" prevents
reprogramming of the device or even the watchdog fuse!

What's the remedy for such situation ..?

Wow, you're right!

Well, here's their website: http://www.carlsjr.com/info/map
(their main site has a whole lot of Flash, just a heads-up.)

Around here you get hammered with ads for the two biggies,
McDonald's, and Burger King, along with VERY annoying commercials from
Checkers. http://www.checkers.com/find.html They are so annoying I
either hit the mute button, or turn the TV off.

You have to use a parallel programmer to effect an "all fuses" reset........

Checkers, huh? Don't have those over here. Your Checkers seems really
similar to our In-N-Outs over here. (In the Los Angeles area, the
In-N-Outs are mostly drive-thru, no dine-in; in Northern California,
there's usually a dine-in area like McDonalds, Burger King, etc.)

Any Wendy's, In-N-Out, or Jack-In-The Box over there?

Some Wendy's. It started in Ohio, and we get a lot of Ohio
snowbirds, so...

BTW, one of the young men who volunteers for my "Computers for
Disabled Veterans" project works at a Wendy's restaurant. He does the
heavy lifting, and I'm teaching him to repair computers.

Have a look at

http://www.avr-asm-tutorial.net/avr_en/beginner/index.html

That give most of the startup details.

They don't want to be in competition with themselves:

The only Hardee's around here closed without notice several years
ago. The employees arrived for work to find the locks changed, and the
place is still sitting empty. I haven't seen an ad on TV for them for
years, either.
