I don't think you'll find a consensus on house-rules. Some groups are happy with the rules "as is", some groups have had a plethora of house rules (the "Bad Karma" set for example [currently not online]) and some have a few house-rules, but many different ones.
I think the best thing is to play a few games within your group (not as part of the campaign), have a chat within your group what you did and didn't like and make your own house-rules around that.
