You don't need more yeast. The yeast reproduce, and you would have plenty of yeast in there.

You should make sure the wine is in a carboy or demijohn, and topped up so there is no headspace and wait for it to clear. This may take a while.

If your wine is still producing a cap (grape skins) that means it is still fermenting. That cap usually gets punched down every 8 hours or so to improve extraction and to keep the skins moist. Once the cap "falls" the fermentation is likely complete. You can confirm with a residual sugar test (Clintest). Dry red wines should finish about 0.1 to 0.2 residual sugar.
