Oh and if you do something involving layers a hairdryer is super useful on paper. It can also help with page curling it gets too wet.
And another thing to remember is that you might not be able to brush as hard as you might with canvas. I also find paper easier to work on if it is on a table or clipboard rather than an easel because it is less sturdy and I tend rotate whatever I'm painting on in different directions.
The thing I found difficult to get used to was working at a smaller scale because I got A4-ish size paper. If you have a similar situation and your are working too large just focus on what does fit. You just end up with a slightly different painting focus or with a changed perspective.
Sorry for rambling. I hope some of my tips help.
