General Issues with my gTablet

So I am here to report that I still love my gtab!! Sadly, I must post my current issues that I have not been able to bypass, hoping for some help...

I am running tnt lite 3.1.4 with clemsys kernel.

I still have no clue where to start with phone tethering - I have a windows 6.3 Motorola Q.

I have AndroExplorer and ES File Explorer which both can see my media share (500gb drive on my network) and it's wonderful - all my music, vidoes, photos... I have found NO media player that can see beyond the local mount, sd card, and usb mount.

I have a blue tooth headset that pairs and works beautifully - but when I turn it off, my gtab can't turn the speakers back on?? I have to re-boot.

 

Also - I am thinking I will load the newest TNT lite 4.2.2. What happens to all the apps I already have and paid for? Does the market keep track? Will they remain on the device?
