HP dv9930us upgrade options

Hi all just trying to get some info as to the possible upgrades that are available for my laptop.
as of right now is stock.
T5750 2.0GHz cpu 667MhZ fsb(Socket P=?)
4 GB ram (understood this is the max)
320 GB hd TOSHIBA MK3252GSX
8600m GS 512MB
17" WXGA+ High-Definition BrightView 1440x900 (single lamp)
LightScribe Super Multi 8X DVD+/- R/RW with Double Layer Support
vista home premium 64bit
..
from what i have read doing research this setup is a configured version of the dv9700t
which has the capabilities of a 8100,T8300,T9300 AND T9500 cpu's all 800Mhz fsb are these possible

the hard drive is a SATA 1.5gb/s 5400 rpm
can i upgrade to a 3Gb's ver.

also the video had an option on dv9700t for the less 8400m GS 256MB so can i upgrade it to a more faster video

I'm pretty sure i can upgrade the LCD to a 1900x1200 via this info

would love to find a dual lamp glossy

is the Blu-Ray ROM with SuperMulti DVD+/-R/RW Double Layer worth the upgrade i do heavy downloading to archiving but watch movies as well.
if anyone knows of a slimeline Blu-Ray dual layer burner that would be great as well

any help with feedback or link info i would greatly appreciate

 

you can upgrade your CPU,HDD,and optical drive.LCD upgrade is possible,but it will void your warranty!GPU upgrade is not possible sadly
