One thing you might want to look at is the Apache Whirr project (which is awesome by the way!).  It automagically handles spinning up a cluster of resources on EC2 (or rackspace for that matter), installing and configuring cassandra, and starting it.

One thing to be aware of if you go this route.  By default in the yaml file all data is written under the /var folder.  But on a server started by Whirr, this folder only has something like 4gb.  Most of the  hard disk space is under the /mnt folder.  So you'll either need to change what folders are pointed to what drives (not sure if you can or not...I'm sure you could), or change the yaml file to point the /mnt folder.

Is there any manual or important notes I should know before I try to install Cassandra on EC2?
