will i ever get a seat travelling in from sevenoaks to london on the train or will I be standing forever.....?

Only if you change your working day by 12 hours! Travel in at 8pm and home at 5am - but still no guarantees!!

Hi it obv. depends on when you are leaving. On my train at 7.50 not much chance I am affraid. But it is not that far really. I sometimes see people take fold up seats.

go outside peak hours and you should or else wear a storng perfume/ aftershave or start behaving oddly - people will soon move away!

You can on the slow train, because that starts at sevenoaks, however, that takes about twice as long as the fast one that only stops at Orpington and London Bridge. Best option is to grin and bear it or move house.
