does anyone know a book/site etc which has numerous q7/8 type questions to work through?

Could you give the whole question? I want to try it

edit oops misread post disregard what i said before for your question, you only use the smaller value of theta to find P because the limits on the question say 0 < theta < pi/2

when we write something with a log, do we write like 1 - ln (x+a) or 2 - ln lx+al

you can also use this to find exact values for cos2pi/5 and cos 4pi/5

are you sure the question is correct? I get the required for arg.(z^2-a^2); trying arg.(z^2-a) becomes a dead end

That's what she said.
