HiYa John,
Generally once I have looked up my relative or Soldier Im researching on the Birth, Deaths and Marraiges registers and got any certificates and then tried the 1901, 1891 census's etc and put flesh on the bones I contact the regiment, then look for military papers.
His Medal Index Card doesn't always tell you much more than you know, especially as he survived, you do need it to get copies of his entry on any medal rolls which can tell you a little more but you will have to go to London and search for them yourself.
I tend to pay a researcher to do this for me, I have used a gentlemen called John Collins over a number of occasions, spread over the last 20 years. If you look at his site,
ERROR://militaryresearchon.com/
He does a package for Soldiers that survived the war, for your money he will get you copies of the medal roll entries and search for a Soldiers Record but to be honest lots were destroyed in the 2nd World War and sometimes you pay your money and take a chance but if they have survived they really are a great source of information and interest. To be honest unless you know the exact dates he served in a certain battalion and regiment you could be looking up other mens histories, I have some medals, to a gentlemen from the 2nd Worcesters, I bought on the chance he charged at Gheluvelt and until I had his service record I didn't know he came home before the battle.
To pay a professional is usually cheaper than searching yourself but there is more chance the service record has been destroyed than it has survived. If you do find the relavant dates I will be more than happy to send you extracts from Captain Staackes History of the Worcesters in the Great War for any periods of his service.
I Hope this is helpful
