Buying train tickets...

I am wondering about the best way to buy round trip train tickets from the US for a day trip from London to Salisbury. I will be traveling with a group of 12, and we are leaving in 1 month. I see many websites where I can view timetables and make purchases, but am a newbie at this and would love some advice about the best route to take to make the purchase.

Are you booking just yourself or everyone? Over 10 people counts as a group with South West Trains with discounted rates.
