Just recoverd ipod touch got cracked screen worked before now wont slide to open or cancel power off

Because this is a fused part (lcd and digitizer) you will have to buy a new screen assembly. BUT before you do that open the the iPod back up and verify that both connectors are properly seated.

If it all looks okay and still does not work then you probably bought a bad screen.
iPod touch 4th generation Cracked Screen Replacement

You most likely might have damaged it by dropping it or hitting it against something while not noticing. What you are telling me are signs of having broken the touch sensor (it happened to me before).
You have one of three choices:

1. If you bought it less than a year ago, go to the Apple Store and they might replace it on the spot for free since I think its covered under their warranty
2. Go to the Apple Store and have them fix it.
3. Go to the Apple Store, give them your old iPod and buy a new one - they will give you a 10% discount.

Ipod touch 8g has power but the slides to make it work only slide part way before returning to its normal position. This is happening with all slide options and I can do nothing to get it to work again, I have tried soft and hard resets, any advice?

Hold the sleep/wake button on the top on the top right until the red slider appears. The slide the slider. If no go, see http://www.apple.com/support/ipodtouch/troubleshooting/ipodtouch/

Hold the sleep/wake until the device powers off.

Use the Five Rs to recover the iPod. You will lose the data that is currently on it if you restore but you can always re-sync the data to the iPod.

you cant crack it but you can surely get your itouch working again

1. Power off the device (Press and hold the Sleep/Wake button for a few seconds until the red slider appears, then slide the slider. Wait for the the iPod touch to turn off.
2. Press and hold the Home button while reconnecting the USB cable to iPod. When you reconnect the USB to iPod, the device should then power on. 
   
3. Continue holding the Home button while iPod starts up. While starting up, you will see the Apple logo.
4. When you see "Connect to iTunes" on the screen, you can release the Home button and iTunes will display the recovery mode message:
5. Restore and it'll download ~240mb firmware and you're done

Warning: you will lose all your data
