I'm a little confused. I have done some research but this merger business has me coming up with a lot of questions and very few answers.
As a DO, you sit for the comlex so to enter an MD residency do you need to sit for usmle as well?
Also, what are the limitations with a DO residency in terms of options? Can I do general surgery or dermatology?
As a DO you must take the comlex. You have the option to take the usmle. You do not need to take the usmle to match into an MD program, but it does make it easier. It's like comparing apples to oranges versus oranges to oranges. I'd recommend all DO students take the usmle. The DO match rate for MD residencies is 75% overall.
Some MD fields are more DO friendly than others. Derm, rad onc and the surgical subspecilities are the least DO friendly. Of the 2000 DOs who matched a MD residency last year, 4 matched derm, 2 matched rad onc, 1 matched ENT, 6 matched ortho, 2 matched neurosurgery. There is no data for urology and opthamology.
General surgery and radiology are probably the next tier, in terms of DO friendliness, with radiology being more friendly than gen surgery. 79 DOs matched MD radiology and 47 matched MD general surgery.
Everything else is relatively DO friendly. However, with that said, no matter how well you do in osteopathic medicial school top programs will probably be out of reach for you as a DO.
In terms of fellowships, about 66% of DOs who applied to MD cardiology and hem/onc matched, and 33% of DOs who applied MD GI matched. These are the most competitive internal medicine fellowships.
Here is data for MD residencies

There are roughly 2900 DO Post graduate training positions offered each year. Most are internships (600), family medicine (845) and internal medicine (570). Most other specialities are offered by the AOA, but there are few spots per year, especially for the high paying specilities. There were 135 general surgery spots and approximately 40 derm spots offered last year in the AOA match.
There were 4913 DO grads last year.
