Almost everything's been covered very well above, but I also found that if the front sprocket is a bit reluctant it could be that the red threadlock is doing it's job a bit too well - I found that the brief application of heat loosens it up a bit; 10 seconds or so around the nut (using one of those blue-flame kitchen doofers for caramelizing sugar is good) and a quick pull with a long breaker bar should shift it.
Good luck
it's a satisfying job when it's completed, but be prepared for unexpected foul-ups...
the first time I did it (on my '12 glee) it took me over 4 hours! - although that was because I also discovered that the rear sprocket carrier bearing had lunched itself and was spitting bits of cage everywhere, and the second time (just a couple of weeks ago) also took me 3 1/2 hours, but this time it was a nut on the replacement sprocket carrier which wouldn't budge - I eventually had to chisel the bastard off!
...still, it was satisfying having done it
also, I used a little dremel (old Woolies equivalent actually) to cut the chain, effortless and quick.
Oh, and I put a damped 16 tooth cog on the front, just to see if the reports were true... (these being better motorway driving and better mpg)..... a thousand miles later, I can say that she does feel a bit less revvy at 70 (~5100rpm) but as suspected, the way I ride has increased the consumption rate [I.e. mpg's gone down from 68/69 to 64/65], but I'll stick with it just in case it's the summer making me more....throttley assertive....
