Finding the best combination of PCIE/USB peripheals (AOA150)

Hi everyone, I've been registered here since i got my aspire one, back in 2009. Now that warranty has passed by, it's time for me to start modding it
I've read so much posts about hardware mods available for my little aoa150 (winxp), but i still haven't found a good solution / combination for my needings

I'd like to add to my netbook
1) HD video acceleration via Broadcom HD Movie Decoder BCM970015 (or should i choose a BCM970012? :? ) (PCI-E)
2) Internal Bluetooth
3) Eventually internal 3g (PCI-E)

i already own a
3G USB sitck
Wireless IEEE 802.11g USB dongle
Bluetooth USB dongle

What i am asking is a suggestion about wich of those 2 combinations would be the best

Setup A

1- Pull out internal wifi card, use that pcie slot for the BCM970015 card
2 - Install an usb micro hub on the the unused usb port on the motherboard's backside.
3 - Connect the bluetooth dongle on HUB's Port #1, and place it on the lcd's left side
4 - Connect the wireless usb dongle to the hub's port#2 and place it on the right side of the lcd.
The antenna wuold be the one built-in on the dongle's board.

Pros
This combination leaves the 2nd pcie slot unused, so i can still go on with the 3g internal mod (as soon as i'll find some courage to start soldering the pci-e)
I could turn off USB bluetooth and USB wifi via dip switch, for power saving, also i think i'll be able to turn off the broadcomm HD using the old wi-fi switch (does it work? =/ )
Low chanches to mess up things, only 4 solderings to make on the motherboard (excluding opional internal 3g card/connector)

Cons
The usb wi-fi dongle becomes very hot, could it damage the lcd ?
Any cons using usb wi-fi dongle instead of pci-e card? (speed, antenna range?)
Some not-reversible moddings, like installing the dip switch in the case.


Setup B
1 - Pull out internal wifi card, change it with a combo Wi-fi/bluetooth card
2 - Solder the 2nd pciE port and use the BCM970015 in it.
3 - Solder the bluetooth dongle on the unused usb port on the mobo's backside and place it near the lcd
4 - keep on using the 3g usb stick (no more pci-e ports) when i'm not at home

Pros
Any cons related to using a pci-e wi-fi card instead of an usb
I think this is a more "clean" solution
Not so immediate needs to use internal 3g so keeping on use the usb thumb would not be a big problem.

Cons
Think i can not turn off bluetooth or at least i can only turn both wi-fi and bluetooth off
Maybe i can turn off the broadcomm hd video card using the already-installed 3g switch?
I'm obliged to solder the second pci-e

so...any suggestion? which one would you go for?
