Woo! 1 Month till scores

(did ECO 3/4)
Hey guys, seems to be a huge wealth of knowledge here, thought i'd tap in
And if you help me here and are selling anything that i'm looking at buying (IT SoftDev, Physics, MMM, English txts and notes -
http://vcenotes.com/forum/index.php/topic,33927.0.html), ill give you preference if its a similar deal

Subjects:
IT Soft Dev
English: Crucible, The Rugmaker of Mazar-E-Sharif, and Ransom (David Malouf). And 'On the Waterfront'
Methods (CAS): Using the nspire
Physics: Using Heinemann Physics
I'm interested in the best ways to spend money on each of those subjects. I'm looking for stuff that will help me go from 40s to 48s, and the less effort the better (though that is hugely contradictory

). If I keep it up, im looking at a 99.
2 qs: what are Jacks Notes and Derrick Ha's notes?
So some of the things, for example: should i get a studyguide for the crucible, rugmaker, and ransom? I already have sparknotes & cliffnotes for Crucible, are the insight ones on this stuff any good? What about for persuasive writing, the context stuff, on the waterfront, etc.
I'd rather get a small number of things for each in the case of studyguides so i don't have too much crossover - so id just get the best one of each. And thats why im posting this - to find out what the best is.
Eg im interested in whether things like checkpoints, tssm notes, certain lectures, etc are any good, which are worth it etc.
And regarding practice exam packs and stuff, i'll probably get some stuff like that. I'd rather get the stuff that will help the most (so current study design), but will only want to buy what I need because theres a lot on here. I'd consider the MHS Pack for $25, I saw that mentioned elsewhere. What exactly does it contain?
On an unrelated note, I am considering three things. How much work (obviously different for everyone.. blah blah.. give an estimate) would I need for a 44-45 (scaled) per week in: Accounting, Physics, Spesh, Further and Uni Computer Systems (Monash). Mainly looking for comparative figures, they don't need to be absolute numbers.
