ok so let me get this str8 /// if i just keep the wallet open on my computer, will it function as a node or please step by step if this is not the caseee
If you keep your wallet on your computer open you are 'Leeching' not "Seeding". Meaning that your Port 8333 is most likely not open for other nodes to see and seed from... Might not be a good idea to open up your client you have coins in:
You can follow a well done script to get a Seeding node up and running on a VPS if you have one or care to get one - they are reasonable priced.
Then follow what Gweedo states for "NOHUP" to have your bitcoind autostart on reboots and when you close out of SSH.
