My suggestion? Yes, cause:

1. Mass Effect will be a trilogy and if you are into the good story, you should finish ME 1st.

2. Combat in ME2 looks more interesting than ME so if you start with ME2, combat in ME might not be as much fun.

3. Read point number (1)

4. Your ME character can be port(is that the right word?) over to ME2.

5. Read point number (1) ... again.

6. Pew pew

Not quite.

Your ME1 plot-based outcomes will be brought to ME2, and they will be generally be side stories to the main ME2 storyline.

If you brought ME1 character to ME2, you'll just get some bonuses depending on the previous ME1 level, but the ME2 character will be a fresh start.
