ETA I'm not sure I'd agree with the comment above that pentecostals are more concerned with the holy spirit than God or Jesus, yes He (the holy spirit) does play a role in the church, but they are a trinity - God the Father, God the Son and God the Holy Spirit. Salvation is through belief in Jesus.
I guess what I was trying to say is that Pentecostals place more of a focus on the work of the Holy Spirit than other denominations.
Lutherans tend to focus on grace - the salvation through faith rather than works (having to do stuff to get to heaven). Catholics have traditionally more focused works for salvation but that's not quite what it was. Lutherans do good works in response to the fact that we are saved. We do have a number of international aid agencies that we as a denomination support that are in troubled areas of the world.

Major denominations also have a range of worship styles within the wider denomination. You have high church (very formal and structured/highly traditional) through to contemporary (with bands, not always with set formats/liturgy) and combinations inbetween.

Pentecostal churches believe the bible is the infalible word of God, as it was written without anyone's additions (like the catholic bible has eg). The version of bible doesn't really matter - everyone has their favourites - they are all the same just in a different tone of language if you like
this is pretty much true for most denominations. When the bible was being written in it's current form, there were some disputes over a number of books in the bible which is why the Catholics have more books in their versions, typically called the Apocrypha. There were a number of criteria that the original compilers placed on which writings/books were going to be acceptable for inclusion and the Apocrypha ones didn't quite meet all the criteria but did meet most. The different versions are just different ways of translating the meaning of the bible - there are words in Ancient Greek & Latin that we don't have words for in English so the translations vary to show the different ways of getting those ideas across.
