John as to the question about 1808 uniforms still in use i could argue that units assigned to the british divisions and later corp would probaly be equipped and in british supplied uniforms but due to the still deplorable state of the spanish logistical system and the requiremnt of regiemntal commanders to supply their own regiments uniforms in the spanish regualr army i figure you can get away with it, i would hardly guess that replacement of unifmrs was high on the list with everything else in shoratge, the impression i get from memoirs and leters form some of the officers presant and the research by esdale, oman and napier gives the distinction of little unforms apperance and though oman and napier could be argued as biased in some sense esdale presnets i feel a more unbiased view and his appraisal of the spanish army and it ability to supply and equip units is highly critical even more so that the british in the early stages of the war. I figure that the three regiements in question might still be easily feiled in the old uniforms i don't think they served with the british formations but i havn't looked so might be wrong but i would still figure that use of the "british" uniform was not wide spread. Haythornwaite suggests in one of his books that it was not universal but then no specific refence to your three regiements.
