John - if you want to focus on just the 1st TF/1BD (all the Munich area targets and area of the biggest battle) that will tell you where to launch from (i.e Bassingbourn for 91BG, Thurleigh 306Bg, Grafton Underwood 305th BG, etc and for FG's the 4th Swept past Stuttgart and returned short of Ulm, the 355th from Steeple Morden arrived near Augsburg, and the 357th from Leiston arrived 10 minutes later just east of Augsburg, north of Munich)..
Don Caldwell's new Day Fighters In Defense of the Reich has a detailed map showing most of the LW Gruppe airfield locations for the engaging fighters on page 275.
Let me know if you got my 'stuff' from 1TF maps and reports
