In real life it's hard to lift a wheel, let alone roll the trike, unless you overcook a corner or otherwise take the piss (emergency swerving to avoid something is how you're most likely to do it). If you keep to the sort of speeds and turn radius you'd use on an upwrong, you'll be fine. I've only managed it once, while comedy off-roading on a muddy canal bank with a ludicrous camber.
Practising lifting a wheel by doing tight low-speed turns in a car park is probably worthwhile, though, if only to get a feel for how it behaves. The Sprint is reasonable graceful about the difference between one wheel lifted and flipping over.
It's mostly the standard recumbent newbie stuff like seat and bar adjustment and pedalling technique, you have to get used to having to consciously tell it where to go with the handlebars, rather than just looking where you want to be as you would when riding a bike, but the process is intuitive, especially if you're used to driving a car. The most important newbie skill is getting a feel for where the wheels are with regard to pothole-avoidance (top tip: if the hazard passes under your foot, it will avoid both wheels), and n-point turns around Silly Sustrans Gates™.
Other non-riding things to get used to are how much of a drop you can safely roll down without grounding the frame; it's something less than a typical kerb height, on a Sprint (a bit of helicopter tape on the bottom of the cruciform is a good idea). Also, pulling the trike around backward by lifting the back wheel, rather than attempting to push it. And - as is standard for recumbents - if doing a more-than-one-person lift, as soon as someone supports the front of the boom (which is something well-meaning people always try to do[1] when you've got to carry one over some obstacle), be aware the whole thing will immediately try to tip sideways. This can be used to good effect to carry the trike through a standard doorway: apply the rear parking brake, one person lifts by the chainring guard, the other grabs the back wheel / luggage rack and controls the rotation.
Standing the trike sideways on one of the front wheels doesn't normally hurt anything (the mudguard might bend a little), and greatly simplifies puncture repair on the opposite wheel.
[1] If they're non-cyclists, expect them to grab it by something inappropriate like a light.
