What kind of climate are you talking about? My impressions are that lowering absolute production and reducing costs seems to be really important in most large scale agriculture these days - fuels and fertilisers keep going up in price - so your plan sounds fairly sensible. Holistic grazing also has the potential to improve land and stocking rates given a few years of application so is worth investigation.
If permanent fences are not already in place you will probably need to invest a bit in some portable electric fencing and think about how you will supply water to a series of mobile paddocks - some kind of water storage on a trailer with a trough?
Water is particularly important - sounds like you should have plenty of scope for putting in some water catchments on an area that large. This will help your animals, but also open up options for alternative landuses if you have sufficient water storage for even occasional irrigation.
On contour swales/ditches will help infiltrate what rainfall you have to replenish the local groundwater - keyline ploughing could be an aspect of this, but if you go for larger swales and ditches you could consider planting some shade/fodder/fruit trees.
