First, you may get errors attempting to edit parts of the project - the cause of this is simple: some files are read only due to the source control. Simply right click on the Project Folder in Windows Explorer and un-check the Read Only flag and apply to all sub-folders and files.
Second, in attempting to deploy the project, you get an error like:
Error occurred in deployment step 'Add Solution': Cannot access a disposed object.
Object name: 'SharePointProjectItemFile'.
This is turns out is a simple issue - simply close the project and re-open it and the error should go away (double check the first issue if it does not work the second time).
