I'm using a Lenovo ThinkPad T61, which has an Intel 4965AG adapter.

That's a 4965AGN, stripped of 802.11n functionality.

Due to some new flakyness on my current router (affecting both wireless and
wired), I am shopping for a new wireless router. ÂWill an 'N' router perform
better / faster for me, given the adapter I have, than a 'G' router?

No. But a router that is capable of 802.11a (basically, 5Ghz 802.11g)
will perform better, because fewer people use the 5Ghz band.

How
can I tell from a given wireless adapter what the maximum speed it will
support, so I can know whether to just stick with 'G' and avoid wasting
money on 'N' which has features I can't take advantage of?

Look up the spec sheet.

Be aware that there's a mutltitude of 802.11n classes - 802.11n is
available in 150 Megabit, 300 Megabit, 450 Megabit. 600 Megabit is
currently planned, but as far as i know, no products have hit retail
yet.

802.11n is also available in 2.4 Ghz and 5 Ghz modes. 5 Ghz has worse
wall penetration, but the 5 Ghz band is used by fewer devices, thus
often offering advanced performance.
