Ive done this now several times successfully, Although I would suggest buying the lcd/digitizer assembly as 1 unit. It is very tedious, frustrating work and the glass
shards are very difficult to clean up - if you have kids don't do it.
It is hard enough to re and re without damaging the lcd/digitizer connectors
If its the only tablet you have, save yourself the headache and spend the money.
fee-bay has them listed for ~$50 USD free ship from China.
