To address your questions directly:

1. I imagine this is in the mixing or the connection to the RX - but at the moment both wheels go forwards or backward but not opposite directions to enable us to steer it!! How do I sort this?

I presume you have one speed controller per motor? The only time I've heard of this happening is when one speed controller is driving both wheels (since the speed controller is mapped to only one channel, it can only go forwards and backwards on that channel).

Assuming it is one per side, I can't visualise a situation where this would be happening because one speed controller is mapped to one channel. Can you show us how the speed controllers are wired in to the RX?

2. It is very sensitive to ramp up the power ie it’s either slow or bloody fast!! Any ideas how I can improve this as my daughter will be driving it and could do with a reduction in sensitivity to help her.

I know some ESCs allow for a exponential acceleration curve rather than a linear one, I guess you are using TZ85As? If that is the case, I don't think the optional programming card work with them when brushed (could be wrong with that). The video suggests it is working OK to me, I'd just get some practice in driving the thing.

3. What are your thoughts on us coming to Manchester? Should we have done more testing or some practice battles - ie do we need a level of competence / experience or robustness to enter?

That is a question only you can answer. You don't need a level of competence (beyond being able to use the power tools you bring, which you evidently can) per se, just sign up and come on the day, it is what I did at Robots Live! Grantham 2017. If you feel able, by all means come, you'll be welcomed by everyone attending I am sure.
