I'm 95% sure that this is a bridge problem. Changing any string, or even tuning a lot with the pegs will pull at the top of the bridge. Any string will affect the whole bridge, so its extremely likely that putting on the G and C changed the alignment under the D, and to a lesser extent, under the A. Don't worry about this, I doubt you did anything wrong. I find myself checking my bridge on a daily basis.
One thing you could do is ask your luthier to make you a bridge guide, just have them cut a stiff piece of tagboard to fit snugly between the bridge and the fingerboard right between the D and G strings. I urge you to be very cautious if you move your bridge on your own, but a guide can be useful to at least clue you into what may be going on when your cello starts sounding sick.
If you do want to try adjusting your bridge on your own you need to use a very specific technique. Place your cello on your lap, back down, with the scroll off to the right side and the endpin off to the left. The bridge should be right in the middle of your lap, pointing up at your face. Place your thumbs across from each other, one on the fingerboard side, the other on the tailpiece side, right at the top of the bridge. Start between the D and G strings. You need to use considerable force, but don't jerk things, slow, constant pressure is the way to go. Some people will show you a different way, where you simply hold the cello like you're playing, and move the bridge from under the strings. DON"T EVER DO THIS!! You have much less control over the movement of the bridge and you risk moving the feet of the bridge, which will affect the sound much more than moving the top.
My first recommendation for strings would be to go to a Jargar Medium, if that makes things a lot better I'd even try a Jargar Forte sometime down the road and try that. If that doesn't work I would try Larsen's for the A and D. They are probably the most popular A and D strings, but I don't typically care for them. After Larsen's, try Evah Pirazzi Soloists. After that try Permanents. Just to re-iterate, I doubt you'll need a new string after you get your bridge realigned.
I'll try to clarify things a bit:
If, after your bridge is fixed, you still don't like the soft Jargar, try the medium.
If the medium makes things...
...better: keep it or try a forte. A Forte might be to much tension for your cello. Mediums are the most common tensions for all strings.
...worse: try Evah Pirazzi A and D, medium soloists.
If you go through all of those strings and like the feel, but not the sound of...
...Jargar softs or mediums: try Larsen mediums. Soloists will be higher tension than the regulars, if Jargar Mediums were better than Jargar Softs, use the soloists, if the softs were better use the non-soloists. Go with medium Larsens either way. They will be brighter and have a rounder sound than Jargars.
...Evah Pirazzi's..try Passione mediums. They are even lower tension and have a rich, dark, pearly sound. I use these and love them.
I'm not sure exactly where Permanents fit in, tension wise, but I know that they are very good when used on the right cello and have a very bright, warm tone.
Larsens are probably the most popular A and D strings today, though I don't care for them. Lots of people really like them though.
Velum, or parchement paper, is commonly used to raise the string a bit in winter, since the bridge drops due to low humidity, or to keep the string from cutting into the groove in the bridge as quickly.
As much as I like supporting local shops, they often have significantly higher prices than you can find online.
Prices do fluctuate, but here's where I commonly shop for strings:
+quinnviolins.com - almost always best price
+iustrings.com - very limited selection, currently only Spirocore Tungsten and Larsen soloist, but by far the best prices
+sharmusic.com
+johnsonstrings.com
+swstrings.com
+concordmusic.com
And one last thing. If you want some incredibly G and C strings, try spirocore tungstens. They'll almost always be an incredible improvement over other strings, such as Jargars.
Sorry for the long post, but there's a lot of information to cover.
