According to Charles S Grant in " The Armies & Uniforms of Marlborough's Wars Volume 1" from Partizan Press, the Prince Philip Carabineers were formed from the remains of the 3 dragoon regiments after the Battle of Blenheim. No further dragoon regiments were formed by the Bavarian Army during the WSS (probably because a lot of Bavaria was occupied by the Imperials.
There are some excellent Robert Hall uniform plates available from the
Pike & Shot Society website for the Bavarians <
http://www.pikeandshotsociety.org/index.htm>and Maverick Models do superb flags in all scales <

As far as strengths go, the only OOB's I have show squadron numbers only.
For Schellenburg & Blenheim I recommend Ian Stanford's "Marlborough goes to War" from Pike & Shot Society. At Schellenburg, Monasterol's Dragoons 2 sqns & Santini's dragoons 1 sqn in Monasreol's Dragoon Bde ( along with 6 French Dragoon Sqn's deployed in support of the foot). Lt Gen Torring-Seefeld commanded 26 sqn's of Bavarian cavalry in support behind the Schellenburg - 6 sqn each of the 4 cuirassier regiments - Arco & Weickel in Weickel's Bde and Costa & Wolframsdorff along with 2 sqn of Locatelli Hussars in De Costa's Bde.
At Blenheim, Von Wolframsdorff commanded 23 sqn's of Bavarian Horse deployed between Oberglauheim & Lutzingen as part of the Cavalry under Compte d'Arco. In the 1st line Weickel's Bde consisted of 4 sqn each of Arco & Weickel Cuirassiers, and 3 sqn of Household Guard Horse - certainly the Garde Carabiniers (? 1 or 2 sqn) and Garde Grenadiers & probably also the Hartschiere Garde though Grant says these were palace ceremonial troops. In the 2nd line was de Costa's Bde with 5sqn Wolframsdorff Cuir., 4 sqn Costa Cuir. & 2 sqn Locatelli Hussars. The 3 Dragoon regiments appear to have been in Munich & Augsberg at the time.
At Ramilles, The Bavarians had Cavalry as part of 2 Bde's - 1st Line Santini's Bde 3 sqn each of Arco, Weickel & Garde brigaded with cavalry from Cologne & in 2nd line in Costa's Bde 3 sqn each of Wolframsdorff, Costa & Pr. Philip Carabiniers also with a unit from Cologne. reference = "Ramilles - Marlborough's Masterpiece" by Neil Litten by Partizan Press.
At Malplaquet there are 12 squadrons of unnamed Bavarian Horse present in the cavalry of the Left - 7 sqn in the 1st line & 5 in the 2nd. Reference = "Malplaquet 1709" by Christopher Scott also by Partizan Press.
Hope this is helpful, Cheers, Rohan.
