No don't get netting- it blows over easily, lambs get caught in the small holes, ripped ears, hang themselves, etc etc you get the picture. Our tame lambs are behind 5 strands of taught polywire and this keeps them where I want them to be although if the battery goes flat they know and within 5 minutes are out.
Aside from bottles and electric fence you'll need somewhere to house them for the first couple months of life, heat lamps for at least the first couple of weeks (longer if they are January/february born lambs), plus creep feed for post weaning, not quite as easy as bottle feeding then turning out to grass
Here's a pic of ours, they are in a paddock at the moment as the field they were in has been cut for hay, I just move the fence in or out every couple of days, as such strip grazing.
