Below are some installation notes that have created, during various installations. This will be added to where required.
1. For backup purposes, it is best to have a SEPARATE content database for PWA with a Site Collection limit of just ONE. This doesn't restrict the amount of project workspaces that are created as they are not site collections.
2. Check the other note sections for things such as PerformancePoint for considerations to make there. These are on this site.
3. If applying server updates, you will need to download the Project Server 2010 update that you want. This will contain the SharePoint Server update. You do not need SharePoint Foundation update!! This is included in the main update itself, unlike 2007 where you needed to install the WSS update beforehand.
