Hi vlangford
If you're going to tackle this yourself then you'll have to treat it as a project, some parts of which will be easy and some difficult.
The first thing I would say is that you might be disappointed in the water flow from your new pillar tap. BTW, if your sink is in a bathroom then it's called a basin.
Generally, you need to break the job down and tackle one thing at a time. For example:
1. Find the isolating valves for the hot and cold services, and shut them off. This can become a project on its own if the valves don't work.
2. Disconnect the pipes from the taps, disconnect the waste from the trap, and remove the basin.
3. Install the tap tails onto the tap and the tap onto the new basin.
4. Install the waste kit onto the new basin.
5. Install the new basin. If there are Fischer bolt slots, then use Fischer bolts.
6. Connect the trap and connect up the waste. It might need altering.
If I were you I'd buy a new trap, 'cos the old one will probably be unpleasant.
7. Connect the water supplies to the tap.
8. Reinstate the supplies, testing one before turning on the other.
To answer some of your specific questions

How do I connect the flexible hoses to the copper pipe as th new tap hoses have \\\"nut\\\" like ends and the pipe wont after I have had to cut them
It sounds like you have flexible hoses with compression connectors, so just cut the pipes at the right height (plus a bit) and you'll be able to make on the connections.
I think the waste pipe is the same height so that shouldnt be a problem.
You might want to get an adjustable trap, just in case the waste doesn't line up as you think it will.
