Sorry, but it's totally irrelevant. There's no such thing as "West Indian conditions" or "English conditions", pitches here vary massively in bounce, variable bounce, turn offered, swing available, atmosphere, amount of wear- just about everything. So do the pitches in the West Indies. When a fast bowler gets carted at the Antigua Recreation Ground it doesn't mean they'll be carted in Jamaica in the next match.
In response to the second part, Swann's in my team ahead of Monty because he can bat. If Flintoff is going to bat at six, they need a reasonable contribution from 8. Considering that finger-spin is irrelevant in so many matches outside the subcontinent (where Monty is shocking anyway), I'd say an attack of [Flintoff, Swann, Anderson, Sidebottom, Harmison] looks superior to an attack of [Flintoff, Broad, Anderson, Sidebottom, Panesar].
