Brambles/Figs and Gooseberry's

Hi All,

I've just bought some Bramble/Fig and Gooseberry bushes.

2* Autumn Bliss Raspberry
2* Black Satin Blackberry
1* Invicta Gooseberry
1* Brown Turkey Fig tree

I'm potting in tubs (1 plant per tub) and I'm looking for advice for trellis etc... ATM the canes are tied together in a vertical manner (about 0.5M high). Should I leave them like this for the winter or spread the canes on a trellis now?

Also, some (the Rasperry) have white fruit on them now and some do not. I understand that I need to prune the Floricanes after they fruit but for the first year I have them planted should I leave them all in case they are predoninently all Floricanes?

Last question. Do I need more than one of the gooseberry and fig trees for polination?

Any other tips would be greatly appreciated!

Cheers
