Ive done this a few times. My first attempt was using EARL's. Its all pretty much straight forward, measure, cut and fit. The only real tricky hose is if you want to braid the top radiator hose. Here you need a braided sleeve to fit over the original hose and then have to cut a small section of the fitting to allow the other smaller fitting that feeds the header tank to shampher in. Otherwise you can use tape, but looks just wrong. Fuel and coolant/heater you can do yourself without any real dramas. With EARL's, any ENZED should have them in stock, dash 6 and 8 mainly, 10-12 for turbo and heater hoses. Make sure the anodize on the fittings appears like new, because they fade very quickly once you fit them.

For my second attempt, it was done right using Speedflow. Go-Gear can help you out here. If using speedflow, I would ask for the teflon braid for at least the three fuel/filter/rail lines to stop any vapour smells that usually occur while using normal braided hose.

Hope it helps.
