Hyperthreading can help stability if turned off, but dont bother unless your trying to reach very high speeds >4Ghz, you will gain more from having it on otherwise.
Just read a few guides on i7 overclocking. Then go and up the BCLK buy a few Mhz each time, check your ram speed isnt to high for your timings, run intel burn test and monitor temps. Then reapeat. When it starts failing you will want to increase the vcore and uncore, possibly a few other things depending on your board (im not fimiliar with it).
Just always check temps with RealTemp or something similar. Around 80-85C under load is where it starts getting dodgy for i7 chips.
You can't really just get someone elses settings and plug them in. It MIGHT work, but you have to realise, every setup is different. More importantly every chip is different - even though the are all made the same, some do better, some do worse (thats why the i7 920, 940, 965 are all the same chip - 940s are just the ones that do better than the 920s in testing).
