First allotment advice

Hi all,

i collected the keys for my first allotment yesterday and would be very grateful for any advice. It's a half plot that was split into two separate long beds by the previous tenant and looks to be in a fairly good condition. I've attached pictures of the front & back views as well as the rhubarb

The right side bed is empty but there is a compost heap at the front ready to use. The left has a patch of rhubarb and a lot of fruit bushes & canes. There are a good number of raspberry canes that look like they might be Autumn fruiting or spent summer fruits, should I cut them all back and see what happens? I'm not sure what the fruit bushes at the front are but I think I'm going to dig them out as I'd rather leave more room for vegetables than have quarter taken up by fruit. Is this a good idea?

Im also unsure if having two beds is a good idea or if it is leaving a lot of unused space for a small plot as it the is a fairly wide path between the two. Would people leave it as two or widen the beds to create more space?

Im ridiculously excited but aware that my knowledge is limited as I've only done some basic veg growing in the garden before now. I had planned to go down this morning but it's raining too heavily!

Apologies cod for the pictures being on their side, I can't figure out how to get them right.
