You will probably need to renew everything rubber, in particular apart from what has already been mentioned the brake line flexibles.
That was one of the objectives I had when I started my rebuild, but actually quite a few of the rubber bits were still in fairly good condition. And new rubber versions are of questionable quality that looks like it'll only last a year or so. So you might want to change quite everything.
I would agree with the above but other than the brake lines (and maybe some of the engine hoses dependant on condition) I would not bother replacing them yet. Get it running and drive it around for a bit and you will very quickly discover which rubbers need to be replaced. It is more of an issue with leaf spring vehicels as they have more suspension rubbers but Other than saftey critical (brake/clutch flexi) I would wait for them to fail, usually very quickly after starting to be used again, before replacing.
For the rest of the vehicle my advice would be the saemas above, some oil down the spark plug holes and bar it over to make sure it turns, then try to turn if over without starting with the starter to build oil pressure, if it is a horrible petrol that stops working as soons as is is vaguely damp remove the centre HT lead, if it is an excellent diesel (ignore everyone who complains about them) keep the stop lever engaged on the fuel pump, this will stop the engine actually starting. I would then (for either fuel) run a fuel hose from a jerry can of clean fuel to the filter rather than using the tank and see if it will start.
Once you have got it running then give it a full fluid and filter service and drain and flush the fuel tank. Once running you will then need to turn your attention to brakes and clutch the servicing of which is no different to if it hadn't been stood for a long time.
Unless I have missed something you do not say if it is petrol of diesel? If it is a diesel it will not start without using glow plugs, my recommendation for those would be run a jump lead direct from a good battery to the coil on the bulkhead.
If it is a petrol, for the price and the fact that you will need to remove it anyway I would put new plugs in before trying a first start.
