That bow is probably from the mid-late 80s. Not a big deal. It'll kill deer. I shot several with a bow just like that back then. Maybe go to archerytalk.com forums and read up. Too late for you to start bowhunting this year, but next year will be great. I don't even hunt with a firearm anymore.
Go to an archery pro shop, but don't buy everything they tell ya at first. If it's a hunting setup, lose the flipper rest and kisser button, and put a whisker biscuit on there. Best hunting rest there is for a beginner. Get some carbon arrows, and a release (lotsa styles, personal preferance really, that's where the archery shop will help, you can try different ones.). Read about broadhead tuning, so your hunting arrows will shoot with your practice tips. Didn't see a rear peepsight on the string, but that'll help too. All of this is pretty cheap. Not sure if you have a stand, but a good treestand is probably more important than a good bow.
