I suppose that you will need to narrow your choice down to a little less than just Europe. If you have problems understanding any other language than English, then I suppose the UK would be for you. While most Europeans do speak English to a smaller or lesser degree, there are indeed places where you'd be well in the shyte if you don't have at least a passing knowledge of the local lingo. Spain, Italy, France and to an extent Germany also.
If you are looking for sun and beach, then southern Europe is for you. The drawback is less developed infrastructure and a bit of chaotic Mediterranean mindset, which I personally find charming but let's say that it's not always a beacon of efficiency. If you are less interested in sun and beach, value personal freedom under responsibility, and is looking for a well organised society, then perhaps Scandinavia is for you. Oh, sorry, forgot you don't fancy paying taxes.
Right, there is also the new EU countries like the Czech Republic which boasts fantastic scenery, great beer and very good looking women. Language might be a problem though, but it's still very cheap (outside of the Prague tourist traps at least) and the taxes are not very high. Neither are the salaries; those two things usually goes together.
Whatever you choose, take up relevant language training, get with the local way of life, and enjoy! If you really want to be accepted in the society, the rule is the same as for any expat in the world "When in Rome ......" and the way "Romans" live in Prague is very, very different from the "Romans" in London which again is different from those in Paris etc etc etc. Europe is by no means as homogenous as the US. But that's a major part of the charm if you ask me. You will need to ask yourself which society would suit you best, and I dare say that starting with the tax bit is a rather short sighted approach.
