Unfortunately its a very theory heavy topic and the formula book doesnt really help.
I always liked drawing planes and thinking of basic Core 4 work when it comes to lines.
Although a little late the two different textbooks used for Edexcel FP3 give different methods you could consider. The line of intersection for example is done by a cross product and a common point in the Oxford book whilst its done through expressing x,y and z in terms of each other on pledger book.
Have a search for the AQA further maths ebooks. They may offer a little help.

what is the best way to do well in this topic, ive got my fp3 exam on monday and finding it the most difficult topic
anyone have any good notes, resrouces etc?
ive done the new spec papers btw
vectors is a bit annoying. I would do a question of each type and kind of rote learn it. i.e. do a question to find the line where two planes intersect, a question to find where a line passes closest to a plane etc...i think te above two are the hardest thing u can get in terms of vectors so just make sure u can do them
