Here's some general advice:
There're more fish, adjusting too much is better than not enough because a lot of players are completely 1 dimensional.
I'd say most people don't bluff, if you don't know the player initially assume they aren't bluffing. Obviously this isn't true for everyone.
Read a book on live tells, a lot of people will say they aren't that important but other people will be using them against you so at least be aware of them.
There's a lot of quite strict rules about raising and calling by putting chips in. If in doubt, verbalise your actions before you move chips around.
It's really hard to stay alert when the action is slow and everyone is going on about the suckout they had at an online freeroll 3 weeks ago but paying attention to what's going on will make a big big difference.
Remember you'll have to be a lot more patient than you would online. Bad beats tend to hurt a lot more because you get so few chances in a night but it is what it is so don't get frustrated
Get an app or something to record results, it's really easy to lose track otherwise.
If you can make enough money to live off online I'm sure you'll beat almost all live low stakes games but if you've never played live I think it's well worth playing a couple of low stakes/freeroll pub games first as practice to get relaxed beforehand.
