Hi Dronnybrewer
I've not done that one but as a general word of encouragement yes, just about any kit is easy enough for a complete beginner. Just make sure you sanitize everything properly at each stage. You'll likely also have to wait longer for it to finish fermenting than the instructions predict.
As for additions, the default advice is to brew any kit for the first time 'straight' so that you have a benchmark to compare with later tweaked versions. And you never know, the un-tweaked first-time brew might just be perfect for you.
If you have two fermenting buckets you could split the wort and add to one half but not the other; that way you halve the risk of doing something that might end up spoiling the whole batch for you, and it will give you a comparison.
Hopefully someone more familiar with this kit will post something more definitive. Good luck with the brew mate.
