1. Does this require any prior knowledge of the Mass Effect series?
2. What races are playable, and what are their specialties?
1. Mass Effect is a series that is
really hard to understad into if you don't start at the first game (at least it was for me), but don't let that stop you from trying. It's a great series.
2. There are a lot of races, but the few you can expect here are;
Humans - The usual.
Turian

Commonly, Turians are excellent sharpshooters and make amazing soldiers due to their society having a very big emphasis on community service.
Salarian

Salarians have hyper-active metabolisms, which makes them think fast and act fast. They make excellent spec-ops agents, scientists, medics, engineers, and other things, but their metabolism makes them very short lived, rarely living past 40.
Asari

Asari are a long-lived, mono gender race. They each live for about 1000 years, and they all have inherent biotic ability (kinda like telekinesis) without the aid of technology. They have the ability to mate with any gender of species, taking the DNA of the partner to randomize the genes of the offspring, which is always an asari. Due to their long lifespans, they have a lot of time to train themselves in the art of war.
Krogan

The Krogan were a technologically un-advanced species, until they were discovered by the salarians who gave them access to more advanced tech. This tech allowed them to better survive on their vicious homeworld of Tuchanka, which led to a massive population boom. Their population swelled so highly that it erupted into a war with the rest of the galactic community (which, at the time, was just he Asari, Salarians, and the Turians), and the Turians were forced to deploy a Salarian-made bio-weapon called the Genophage, which rendered only 1 in 1000 Krogan pregnancies fertile. Their rebellions have died down since then, and they are able to live among other galactic species without being feared as dangerous rebels.
Quarian

The Quarians lived on a planet where all diseases were at least partially beneficial, so their immune systems dwindled in comparison to other species. They were forced to leave their homeworld when their inventions, the robotic AI species known as the Geth, rebelled against them. Now that they can no longer live on their planet that supports their weak immune systems, they are now all forced to wear environmental suits so that they don't catch diseases and infections. No one knows what they look like under the masks.
Batarian

Not much is known about the Batarians. They are usually regarded as space pirates and slave traders, but a few live normal lives outside of the galactic council space. They are rarely seen in council space at all. A great number of them join merc groups.
Drell

The Drell are a reptilian species that lived on a planet so arid that remembering where resources were was absolutely essential. As a result, all Drell have near-perfect memory, and some of the slightest outside interaction can trigger powerful memory recalls. They were rescued from their planet by the hanar race once it became uninhabitable, and now most live in arid dome-cities on the rainy planet of the hanar.
Those are all the important bipedal races. If you need more info you can try the Mass Effect wiki.
