Nothing like buying first and figuring out later.

I've probably
done it myself a few times, but I try not to.

Yes, you can daisy chain them if you need to, but your diagram above
made it look like one is hanging off in one direction while the other
is hanging off in the opposite direction. If you do need to daisy
chain them, then yes, the gateway IP of the second one will be the IP
of the first one, while the gateway IP of the first one will be the IP
of the router.

I guess it depends on what and how you're testing. If this is all
about Internet access, then you might be OK, depending on how fast
your Internet connection is; i.e., how much of a bottleneck it is. If
you do intraLAN file transfers across the daisy-chained link, you'll
likely be disappointed.
I recommend tools such as jperf or iperf (google them) for throughput
testing.
Under the best conditions, an 801.11g wireless connection should net
about 24 Megabits per second. Add a range expander, AKA repeater, and
throughput should be cut in half because the repeater can't receive
and send at the same time, so now you're down to a theoretical 12Mbps.
Add a second repeater daisy-chained and you'd be down to about 6Mbps,
but that's ignoring all of the interference flying around, so you're
more likely down to 2-3Mbps, if that.

I'm in the camp that says use a range expander as a last resort. Every
other way of expanding a network is probably better, IMHO. But by all
means, go for it! It's all about learning what works, and you may be
pleasantly surprised.
