The only perf page I use from the secondary flight plan is the 'landing page'. This probably is company specific as well because we use the secondary for the EOSID and others may use it for a different rwy.
I normally take the ATIS weather and put the QNH, temp and wind on that page together with the decision altitude for the ILS selected in the secondary flight plan.
In this case you don't need the 'take off page' from the secondary because when you're in an engine out situation you'll normally continue your climb to at least your single engine acceleration altitude. This normally is 1000' AAL and it's already on the PERF page. When the engine is secure and you reach the SE accel alt you push V/S to level off and accelerate to green dot, activate the secondary flight plan to follow the EOSID and retract the flaps.
Be aware that this is just a general engine out profile as there can be all kinds of variables on the EOSID.
