Ha yes that was me in the Fantasy!
Enjoy the Spurs experience tomorrow - I am a season ticket holder there but a fairly large chap so have tried to fine tune my trips there of late to involve less walking!
I usually get the 185 to Vauxhall and then jump on the tube to seven sisters, then there are four diff buses (all ending in 9) that you can get from there straight to the ground, straight up the high road - although if you leave it too near kick off, they shut the road off (about two hours before) so you may have a bit of a walk (a lot do do the walk, but it is a good mile and a bit!). Would advise getting to seven sisters about three hours before ko if want to avoid the walk.
Another option is get train to London Bridge and tube to Liverpool Street (or bus to liverpool street) then train straight to white hart lane. these will run right up to kick off but involve a bit more walking.
