Sort the hoses out as soon as you can tape won't fix them as there is a LOT of pressure that goes through them - leaking hoses will do the turbo no favours. eBay seems to the cheapest place to get silicone ones.

Definitely blank the EGR - on an 02 Mondeo it will cause no issues at all, and will improve the car.

If you want more power, a simple remap will work wonders - but if the clutch/DMF is tired it will finish them off. If they've been replaced not to long ago then they can take the increase in power without any issues.
