Planting advice please

So my project is going really slowly , mainly due to the relentless rain fall .
However , I have been collecting plants for the past 6 weeks & need to get them in the ground & now that the fencing above the wall is up & the borders are in place I can start to plant 🤸🏻♀️🤸🏻♀️🤸🏻♀️ Also , as my garden has looked like a tough mudders course for weeks I’m bursting to do something creative.
So I'm after two pieces of advice from you more accomplished & experienced gardeners .
the first is ... I’ve had top soil delivered , should I nourish this by mixing compost into the top soil before planting or is fish blood & bone mixed into the planting hole sufficient - or should I do both 🤷♀️ I feel that I should do something but don’t want to meddle unnecessarily.
The second question is ... I’m going to plant climbers intermittently along the borders hoping to have them scramble along the fence ( I’ve tried to show this in the second picture ) I have a variety of clematis, jasmine,honeysuckle etc but I’m not sure as to the best way to encourage them upwards , once planted some of them won’t reach as far as the fence. Should I attach a fan shape trellis to the fence & train them up that or should I attach wires from the wall upwards or is there a better way ?
I hope that the photos help , I appreciate all feedback as well as advice as I’m a total novice . Many thanks x

I hate to throw a spanner in the works..BUT is the fence yours?
The supports appear to be on the back of the wall indicating it belongs to your neighbour.
They may not be happy to have plants all over their fence.
You will not be allowed to put hooks/wires on it to train it.
A friend had this trouble .
It ended up getting very nasty/solicitors letters and a move out.
