After installing the fixes you need to run the SharePoint 2010 Products Configuration Wizard on each machine in the farm.

According to some blogs it says

For the 2010 Server Products it is sufficient to install the SharePoint Server 2010 package as it includes the SharePoint Foundation package.

However i would suggest to go ahead and try to install both MSF and SP 2010
