Blocks Folder and blk00000.dat files In my Bitcoin Folder I found on my old computer,theres also files of  aprox. 130 Mb .dat files. I have now, like I was told dumped the wallet.dat into my new installation of Bitcoin Core, and its running.

Will I need those blk000xx.dat files for any reason ? Are there any cions in them, or information of any value ?
those block files are your copy of the blockchain. you could stop your new bitcoind daemon and move them into the $HOME/.bitcoin/blocks folder and restart bitcoind, and save yourself and the network the necessity to re-download them.
