vinyl guy here (6000) lps and counting .....
First off, your grandmas' 'table will probably be a fine starting point unless it's something like a kids' 'table.
As briank mentioned ... you want to be sure the needle is in decent shape or it can ruin every record you play with it.
Let me know what kind it is and I can definitely give you some help.
Briefly, for right now, you have to run it into a stereo that has a phono input because the signal has to be boosted and the RIAA curve has to be implemented by a phono-preamp. If your stereo doesn't have a phono input you'll have to get a phono-pre which start at the cheapest, around 30 bucks.
If grandmas' player is all in one (speakers and everything) then there's a phono pre in there.
A wall mount is useful if you have suspended floors because it will stop it from skipping every time you walk across the room.
If the house is on a slab then it's not really neccessary.
Later on you start to get into things like belt-drive is better than direct drive ...... a high mass plinth helps get a more neutral sound etc.
Right now these things don't really matter for you yet.
So let us know what grandma has and we'll help you figure it out.
And, if you don't already .... start watching Top Gear!
