you see to be on your way - sorry I did not spot this sooner!
I use KH Diamond, CS2, CB2, and Spotlight strings, and have for several years now.
Some thoughts to get you up to speed quickly...
1) use the combination patches, e.g. all articulations, all sections, and purge them completely before you start. Then add only the articulations and/or sections you need. Big time saver, and sometimes sanity saver (that lovely noise - I've heard it!)
2) don't wrestle with the included impulses. There are a couple that are quite good, but mostly they aren't - not sure if that is the impulses themselves, or the Kontakt engine, but you'll work faster if you use the reverbs that you know and love.
3) workflow - there are probably a dozen ways to use CS2... I create two MIDI tracks, one for the five parts (Vln1, Vln2, Vla, Vc, and Bass), and one for key-switches. Used to use 10 tracks, and there are some advantages, but lately I'm using MIDI channels to separate things, and it is working out quite nicely.
4) The strings are recorded very intimately. Which is cool, you can create a wide array of sounds, but be very aware of timing, as it will change as you apply effects, or rather it will seem to change. It doesn't really.
5) The Adagio patch is really good for roughing things in, then go back and play with the other articulations.
6) If you don't need the legato leave it off for this project. Many of the other patches do a really convincing job of legato, and getting the Smart Legato to behave was on of my bigger frustrations. UGH!
FWIW I picked up 8Dio Agitato and Adagietto this year, and I find I am using KH CS2 less, but it is still in the template, and it still gets used. Several of the CS2 articulations layer beautifully with the 8Dio strings.
Of all the cool tricks that 8Dio use, by far and away the coolest (to my ears) is their dynamic bowing patches. Imagine if you will capturing the actual speed and direction changes in the recorded samples. I know, we are all quite used to using CC1, CC11, and others to simulate these things, but I have to say, I used the dynamic bowing patches for the first time this morning, and I'm blown away at the results. If I were in a hurry I could skip over the polishing phase entirely, I won't, but could, it sounds that good right out of the box.
I got a LOT of mileage out of Kirk's libraries, and expect that I will get a lot more, I will probably upgrade to CS3 when funds allow. The current libs require a little more work than some newer offerings, but that's to be expected as developers extend the whole concept of sampled instruments. But I still like the KH libraries, they will serve you well.
In the meantime, if you run into challenges, and the schedule doesn't provide the luxury of digging around pm me or post and I'll be glad to answer what I can. I'm guessing I've hit many of the challenges already<G>!
