FB, get a chromatic scale picture of the fretboard like this one: http://www.google.com/imgres?imgurl=http...wAg&dur=141
Your capo is on the second fret so just count up two from the chord. So A is B, E is F#, Bm is C#m and Bsus2 is C#sus2. If the capo is on the third fret add 3 and so on.

So with the chords B, F#, C#m and C#sus2 my guess is that the song is in the key of F#. Are there any other chords in the song? What is the last chord of the song? Usually the last chord of the song is the key of the song.
