I personally don't think you can do all of these places in 2 weeks.
You will need 2-3 days in both Battambang and Kampot. Both are great places with a lot less tourists than the other destinations.
Also, unless you want to see all of the gruesome Khmer Rouge sites you can easily see Phenom Pehn in 2 days.
If you will be hitting other beach destinations in SE Asia than I would skip Sihanoukville.

Thank you so much for the advice! I only mentioned all the other places (not Siem Reap and Luang Prabang) because on travelfish it's got a suggested 2 week itinerary with those places, just no suggested time to spend there.
We'll actually be volunteering in a school near Siem Reap for 5 days. However, volunteering will only start in the afternoon so do you think if we're only volunteering from say 2pm-5pm we'll have enough time to see Siem Reap over those 5 days? Or do you suggest we stay for a day or two longer, so we have some extra full days to see things we may not have yet?
What's there to see in Battambang and Kampot? Are they similar places?
Could Sihanoukville be a day trip out of Phneom Penh? Or do you think maybe it's too far for just a day trip? Perhaps one night is sufficient? (after all we will be spending 10 days in Koh Phangan)

Really appreciate all your help!!

I didn't care for Phnomn Penh much; partly, I think, because there were a lot of very seedy characters around (western ones, that is) and partly because both my wife & I went down with food poisoning less than 24 hours after arrival. First and only time we had this in 4 months of travelling in the region. The Killing Fields museums are a must, of course, though are harrowing, to say the least, but its important you go. But I agree that much more than 2 nights in the city seems excessive.

Seam Riep, however, we loved. It is true there are A LOT of tourists there, but we really liked it. There is a lot to do both in and around the town. We spent 5 nights there and had a 3 day pass for the Angkor temples. We weren't sure whether scrabbling around temples was our thing, but we absolutely loved it. Getting up at dawn to beat the crowds to some lovely places to watch sunrise, talking with the kids who sell postcards or books, travelling by tuk tuk through the countryside, seeing temples away from the main ones, going to the Landmine museum, visiting an orphanage. We actually ran out of time there and could happily have stayed longer.

The town itself was a surprise, also. Didn't expect much, but it has some very nice colonial architecture, some very good restaurants (all those tourists) and bars and a very good market in town.

I can't comment on anywhere else in Cambodia, I'm afraid, as we didn't go.

Really wouldn't bother with Sihanoukville considering you say you're going to Koh Phangan as well. Beaches arnt great and there just seems to be an underlying feeling of seediness to the whole place. Just think there are better places to see in Cambodia, unless you're desperate for a beach

I ended up spending a large portion of my time in Sihanouk ville because of the party and backpacker scene. If you are young and into that kind of stuff, then I would advice you to allocate more time to Sihanouk ville.

I only did two days in Siem reap (one for the temple, one for the sightseeing), two in Phnom Penh and then a week in Sihanouk ville for snorkeling, visiting the islands, parties etc
