if you install lotro from the SoA disks without the codes then you will get nothing except a headache from all the patching that is required
if on the otherhand you have a new unsed boxed copy of SoA which includes the unused codes then as above you will get 30days of game time as ViP, you should note that EU codemasers copys of SoA obtained in the EU will not work
regardless of whether you have a code for SoA or not you would be highly recommended to download and install from the latest full installer which can be found here. also if the disks are for the EU codemasters you will need to use the full intaller as the DvD's will no longer work http://www.lotro.com/support/download-lotro
