If he is top 32 at the time then I think his bonus points would be:
100% of all grass tournaments in 2011: 455 points (385 Wimbledon QF, 35 Nottingham SF, 35 Nottingham SF)
75% of best grass tournament in 2010: 35 points from Wimbledon R1
Maybe StatRacket can help out, because I don't know if points from challengers are for sure counted or not..
I'm not sure of this either
. It's pretty rare that someone is in a seeding position has grass challengers on their ranking breakdown.
