When it comes to 737's I can easily differentiate between a 737-200(because of the engines) and a 738 and 739 (they are much longer than the others), but I was wondering if there is a way to tell the difference between the ones in between the 732 and 738/739 such as the 733 and 735 etc purely by looking at their outside appearance. I often see 737s when spotting and would like to be able to tell what model it is. By the same token does is there a way to tell the difference between the various md-80s barring the dc-9 and 717 which are easily identifiable. Thanks.

The B737-300 and B737-600NG look almost the same length, the tails are a good way to tell them apart as mentioned above. A good way to tell the difference between the "Classic" 737s and the "Next Gen" is that the engine nacelles are not as "squished" on the Next Gens as on the Classics. The longer legs of the Next Gen allows a rounder intake because of better ground clearance.
When it comes to the MD-80 variants, it's almost impossible to tell many apart because the changes are not external from model to model.
The MD-90 is pretty easy to spot, due to it's long skinny body and huge tail-mounted V2500 engines.

Might as well go to boeing.com (or airliners.net?) and see how long each of the 737s are. Take a look at airliners.net photos and compare window counts on the 737s; the -400/-800/-900 have two overwing exits each side, the other 737s have one.
Viewed from the front the -700/-800/-900 lack the landing lights beneath the wing, on the flap tracks (though that's no help if the flaps are retracted). The bottom of the nacelle is more flattened on the -300/-400/-500 than on the later ones, but it's not a glaring difference. The big difference between the -600/-700/-800/-900 and earlier ones is the wingspan.
MD81/82/83/88 are externally identical AFAIK; the MD87 is of course shorter, and it's the only MD80 that has that extra bit of metal at the top of the fin, above the tailplane.

Regarding the 732, its easy because of the long JT8D engines.
Concering the 733/734/735: if it has 2 overwing exits, its a 734, I can distinguish the 733 from the 735 by counting the number of window between the foward door and the windowless airframe a bit before the wing, the 735 has less windows as it is shorter (the 735 is approx the length of the 732).
On to the 736/73G/738/739, its all a matter of length, the new family has the larger tail, as stated above, the 736 is similiar in size to the 735 and the 73G is the same as the 733, so the window count approach works (also there are very few 736s around so its easy), the 738 and 739 are simply much longer.
Concerning the MD80, its hard since the 81/82/83 are all the same externally and just about the same as the 88, the MD87 is shorter. The thing with the MD80 series is the tail cones, some aircraft have flat cones and other have the pointed ones, and it seems to be quite random, depending on when the aircraft was manufactured or it is was retrofitted, and not which type.
I thought this was as easy question: what is the difference between a 737 and an MD80 - just kidding, regards.

The 737NGs have the pitot tube and AOA vane that used to be located directly under the cockpit window moved forward several feet. Almost to the radome. Also the nose gear door is closer to squared on the bottom.
As for the MD-81/82/83/88, you can't tell a difference without a tail number or knowing that a certain airline only operates 1 of the type.

The tail bumper is not present on the -500 and -600 models as their short fuselage length makes a tailstrike during rotation very unlikely.It's there on all other models from the -300.
The NG versions have a completely redesigned engine pylon and mounting which also increases the ground clearance.

Knowing what airlines fly what helps the most:
AA is easy, they're all 737-800's
UA : 200's are easy to ID, plus the 500's are much shorter than the 300's
DL: 300's & 800's (a little more difficult)
SW 200's (easy), 300's, 500's (easy), & 700's
CO is difficult since they have 300's, 500's, 700's, 800's, & 900's
US: 300's & 400's
