Hey Mark,
Unfortunately I don't have any book recommendations but I'm sure they exist. Having just done US->UK I agree the UK tax forms are easier to read than at home.
I think there is a somewhat different philosophy between the 2. The UK (banks, HMRC, etc.) seems to do more of the work for as you since taxes are taken automatically from interest, etc. The IRS in the US puts all the burden on you during filing time. The only exception here is that for employed people they both do PAYE.
Sometimes when I want to experiment and learn about US tax stuff I play around with the electronic filing vendors (turbotax.com, taxact.com, hr block etc.) because they have made a business out of making it easier to enter data and populate the forms. Most of them let you walk through steps and enter numbers without paying anything (you only pay to file).
May not help much but my 2 cents.
