The embassy has nothing to do with USMLE. Contact ECFMG on where they are offering the test.

I believe only step1 is offered overseas, all the others (step2CS and step3) have to be taken in the US.

DON'T EVEN THINK ABOUT IT. IF YOU ARE LOOKING FOR A WAY TO F&**@@ UP YOUR CHANCES TO EVER RETURN TO THE US, THIS IS THE WAY TO DO IT !

You are visiting your aunt, period. You get an invitation letter from her, she might have to file an affidavit of support (I am not sure about that). You have to assemble some stuff like your rent receipts, work papers, the deed to your property etc. to show that you have roots in your home country. It might be difficult, but you should be able to get one or more tourist visas.

It is usually not interpreted in that way. People do get B1/B2 visas for steps and CSA. It might be harder from Sri Lanka though.

No, it probably won't be enough. Not unless you start dabbling with extensions of stay. The interview season is usually in the fall from the end of september into December. You don't want to be stuck interviewing and taking the steps at the same time. Waiting on a visitors visa till june to start your residency is too long a time on that particular visa.
I know some Nigerians who tried to pull this off. One managed to do it, the other one overstayed her visa and is now in a unsalvageable situation.
> Or would it be better to make two trips?
At least two.
> One for step 2 cs and ECFMG registration
What do you mean with ECFMG registration. You don't actually have to go to ECFMG at any point in the process (they don't want you to go there, you would see how they blow out your hard earned money on a lavishly appointed office suite in downtown Philadelphia.)
> and the next for Step 3, residency applications and the match
Again, you don't have to be here for the applications per se, or for the match. The applications get filed electronically. It helps to have a US address on your application (e.g. your aunt), but you don't have to be here.
You have to in the US for step3 and interviews, probably for the months of october to december. After that you return and wait for the match (in march). If you got a slot, you have to set up your visa through the hospital for a start in July. (If someone offers you an H1b position out of the match, you grab it and hold on to it for dear life.)
