1. Can I change my job after 180 days of 485 pending, I140 approved
I guess YES - but is this 'YES' based on interpretations or os it a sure
shot thing, fully supported by law.
2. Can the job title change a bit (keeping the same job functions though).
3. Can the current employer create any kind of problem.
4. Also do you think USICS will keep up keep the current rate.

As things stand currenlty, you are eligible to use AC-21 once the I-140 is approved, and once your I-485 has been pending for > 180 days (from the time it was filed, not from the time the I-140 was approved). I'm not aware of anyone who is advising people *not* to use AC-21 in this situation -- it's generally accepted that this is "safe" as long as the new job matches the one for which the GC is being done.
That said, if you don't have a compelling reason to change jobs, you are probably better off to stay put as switching jobs could delay your case by generating RFE's and putting you in the position of having to prove that the new job matches the original one.
There was news recently about possibly dropping the requirement that the I-140 be approved for AC-21 to apply. I haven't heard anything official about this yet though. Some people have used AC-21 even though the I-140 wasn't approved when they switched but without a USCIS bulletin to say this is ok, I wouldn't chance it.

This is where it gets tricky. As far as I know the important thing is the actual job category (e.g. software engineer) and the actual duties performed. The salary probably shouldn't change too much although depending on where the old / new jobs are located it might be easy to justify even a 20-50% change. I don't know how much detail they go into (e.g. if you were doing Java development for web-based software and now you are programming in C++ for a game company -- are those jobs similar enough?).
There's a link somewhere to the actual description of how AC-21 works -- maybe someone could post it.

If the I-140 is approved, the employer can withdraw it but you will have a chance to respond to the NOID (Notice of Intent to Deny) with your AC-21 information (assuming you qualify). If you think there is a strong chance that the old employer will withdraw the I-140 you might want to "preempt" this by sending your AC-21 information in even before this happens. Some prefer to wait and see if any problem comes up though as filing AC-21 might increase the chances of an RFE (which would slow things down) and there's a good chance the approval might have gone through otherwise.
If your I-140 isn't approved and your employer withdraws it you're out of luck.

Very hard to predict. They seem to be going after some "low hanging fruit" currently, approving some applications with NDs as late as Aug/Sep 2003 or even Oct/Nov 2003 or later but there are still many people with an ND of Sep 2002 or earlier who haven't been processed yet. My own ND is 10/23/03 and I expect to be processed in 1 month if I'm very lucky (e.g. if my case is considered to be "easy") and in 12+ months otherwise...
My gut feeling is that they will do their best to avoid getting into the 2-3 year backlogs again but this could be affected by any number of things.
