Any input   

No worries..... If you have any problems pm me and I will help where I can

To be honest you can reuse the injector pipe..... It's good practise to replace the pipe after its been undone but I have reused them to save customers money in the past and also when the parts department forget to order them in.....
There are so many horror stories about injector seals on the Internet so take most of them with a pinch of salt...... Sort out the injector seals and regular oil changes and you should be fine.

Looks like either injector seals or the top cam cover seal has failed..... I would do the top cover 1st and clean up the mess then check it after a few miles.....

That is carbon build up from a leaking injector seal....... It needs to.be sorted as it can cause all.sorts of problems if you just leave it.
If you have the engine running you will be able to smell exhaust fumes from it...... If you leave it too long you will have issues removing the injector to repair it...... I've done loads of these in the past and it's a little involved to sort out.
Best tips I can give you is to back off the 2 Allen bolts that secure it in the head and then give the car a good drive up the road to get it really hot...... And hat way the carbon will go sticky and loosen up enough for you to remove the injector.......
When it's out you need to clean the hole the injector came out of and take care not to loose too much dirt down in to the head of the engine......
Also make sure you have the copper washer off the bottom of the injector out of the head.
There are 3 new bits you need
1x copper washer
1x plastic spacer / coller
1x rubber oil seal
These are cheap enough to do but I normally do all 4 injectors in 1 go.....
Also you will need to clean up the body of the injector so it's spotless......Take care around the injector tip as it is easily damaged..... And then give it a good coating in copper grease to stop it from seizing in the head and making it much easier if you ever need remove them again.
And when you fire the engine up after doing this you will find it will misfire / clatter and splutter smoke for a few seconds...... That is normal..... If it continues to splutter and clatter double check your work and make sure everything is connected correctly....

Just a quick sub note.... You won't have the Allen bolts on this engine you should have a clamp which holds the injector in but everything else is like I 1st said...... Not a bad job to do but you do really need to do it.
