Apologies for the delay in replying
This is good advice although, personally, I don't think he should be worrying too much about getting the lie of the clubs adjusted at this stage.
BL - Definitely get the length that suits you, as has been pointed out you will pick up longer clubs on ebay, Gumtree or the golf selling pages on FB. From there I'd be looking to go for a few lessons before fannying about with the lie of the clubs as you could end up needing to adjust them again.
