Should I go to novice programming or intermediate?

[codesharp]

I've a checkered training history, and I can't make the best of it. I'm hoping you'll be able to help. It's a bit complicated, so do bear with the slightly long explanation.

I've underwent some strength training as part of my (former, national level) kickboxing program. Around 2.5 years ago, I suffered an injury to my cervical spine which put an end to my kickboxing, but also cost me most of my strength. Over the past year and a half, I've been working to regain said strength, and I've managed to get most of it done. But now that I'm at a decent starting point again, I'd like to train for powerlifting.

My current lift maxes are 150 kg (330 lbs) for the squat, 200 (440 lbs) for the deadlift, and 120 (264 lbs) for the bench press. I understand this is not very strong, and certainly not for a person at ~91 kilograms (200 lbs) at a height of 183 cms (6 feet). I've never undergone a linear progression at training; most of my lifting, over the past year and a half, has consisted of a single squat session, a single deadlift session, and a single bench session every week. Weight was increased monthly, with a deload after 3 weeks. I did this simply because that's what I knew how to do, from my experience in kickboxing.

Now that I want to get strong, I'm wondering if I should simplify this programming? And if so, in what way? Should I go back to a Starting Strength linear progression? Or is that maybe too optimistic, and should I do a different program, instead?

Thank you for your help!
