to be able to disassociate myself and limbs as food would be the ultimate goal, so i can interact with them safely so i can move them if need be or check them out for health maintain enclosures etc..
That is doable and easy as long as it is you doing the interaction, for by the time they're adults you'll know what triggers a feeding response and how to avoid making those moves. The important thing is never to become complacent. We all do it at some stage and that's when accidents happen.
in the early stages how you go about first getting them to touch you on there own accord without biting you
I start off when they are young and use gloves. Often I'll put one gloved hand down, palm up, and dangle food above it from forceps held with the other hand so the monitor has to crawl onto the glove to get the food. It's important that the gloved hand entering the enclosure is moved very very slowly and that the food and glove don't touch. The monitor will usually tongue flick the glove and the odd one will try to bite it (it's actually quite unusual, in my experience), so I'll just give it a gentle flick or chuck on the chin with a finger to discourage it. Not enough to freak it out, just enough to stop the bite. It doesn't take long for them to separate glove from food. Later I'll start to dissociate the glove from food and put it in there when there is no food. After that I'll start introducing my ungloved hand gradually. It's best to start with a flattened palm facing them, which is harder to bite than fingertips, and let them tongue flick it. Watch their pupils to make sure they don't suddenly contract, which means they are about to take a bite, don't let them repetitively tongue flick the same spot for too long and never let them nudge a part of your hand with the tip of their snout. On the whole, they're not really bitey animals if you do the right things (at least, lacies aren't), but things go pear shaped if there is fast movement or food smells on your hand. Then all bets are off.
To give you an idea about what I was talking about in my previous post about feeding response/trust etc: My monitors are allowed to wander around my home, whenever I am here to let them out, and have been doing this for years. They wander around checking things out and I just carry on doing what I normally do. One day I was ironing some clothes while wearing a pair of thongs. I finished ironing and was putting away the iron when the electrical cord dropped out of my hand and the plug hit the floor with a thud. Not something you'd normally even think about, but the movement caused my male lacie to come flying across the room in half a second and before I knew it he was right next to my thong clad foot with his head darting around in food-brain mode. This is not a good scenario to be in with an adult lace monitor. Had I moved, I could have been bitten and even a simple bite can lead to severed tendons, arteries and nerves. All because of an electrical cord hitting the ground. Now I wear shoes or boots whenever the monitors are out, just in case. On another occasion I was cleaning my computer monitor with a white dust cloth and the same animal saw the movement. Small, white and moving - has to be a rat, right? I felt his claws on my leg and looked down to see him looking up at my hand intensely, with his arms wrapped around my jean-clad lower leg. Any movement and he would have been running full speed up my leg and straight for the hand holding the white cloth. Without moving a muscle in the arm holding the cloth, I gently pushed him off my leg with my other (boot clad) foot and waited for him to get over his food response.
The thing to keep in mind is that they're not always like that and those are just two sample instances out of hundreds of uneventful days of them being let out, but all it takes is one incident for a bad injury. As a consequence, I no longer let them out of the enclosure when I have guests over (unless the guests are reptile keepers themselves and appropriately shoed).
