Uhhh, my grape seeds are not viable after one year stored at room temperature... if I were you I would preserve them in the refrigerator to extend their viability.
Regarding tips, it is hard to say because there is little information about what you are trying to accomplish... is it for a school project? Are you trying to grow a vineyard? We don't know.
But if it is for some school project you need time... maybe months to stratify the seeds
If it is for growing a grapevine the only tip is:
Do not do it.
Most likely you are not going to get the same kind of vine and grapes as the parent plant... that is why grapes vines are always propagated through cuttings or grafting... always. I mean, I know... after all, I've been since my seven years old with my nose in the wine subject... no, I'm not an alcoholic, I'm a wine producer.
Anyways, if you are growing grape vines better cut the water a bit once they develop... they don't need as much water as other plants, put them on a south facing slope... they tolerate poor soil better than other plants.
Every fall after i make wine I take the mashed up skins and seeds and plant them, I had 100's of seedlings pop up. I haven't grown them out yet, but I'll be growing them up on my fences and dead hedges around my property. I can also use them for rootstock.
I would think they require a moist, cool place to stratify. I direct seeded so they can freeze through the outdoor stratification process.
Unlike trees which often cost $20+ through the mail, grapevines are fairly inexpensive. A few years ago I bought vines from Double A Vineyards in upstate New York. If you buy 50+ vines, you are looking at only paying about $3 a vine, and they have a huge selection to choose from.
Trying to grow fruit trees or grapevines from seeds can be a fun activity, but as Jorge suggested if you are trying to get high quality fruit growing from seeds may not be the most efficient use of your time.
