yes i would use the compost that ya have if it is really good stuff this will help i would also get some perlite and mix 50% perlite and 50% compost mix it alltogether and use this i would take a hand spade and dig ya hole outside where eva ya are gonna do this and fill it with this mixture
then give them a good watering to help them settle in to there new home
i wouldent bother about proper soaking the soil if you are gonna be able to visit everyday and you only need to water every other day anyway
cheers all
