The answer is yes. You do need to supply your own runes.
To get runes, you can either buy them from the various magic shops around Runescape, on the Grand Exchange, or make them from rune essence and pure essence at the runecrafting altars hidden around runescape. If you need help, my runescape username is Xeyran.
It can do several things; read the announcements on the RuneScape forum. What I find especially interesting is that you get several uses of High Alchemy per day, for free, i.e., without runes (nature runes usually cost somewhere around 200-300 coins each). You do need to have the magic level, though.
That is "telekinetic grab". Look in the spellbook. You need magic level 33. Once you have that, you need law runes and air runes to actually cast the spell.

4 Astrals, 2 Deaths and 10 Earths.

The best way, if your a member is to craft them yourself. You could always buy them from shops or other players, finally many monsters drop them. in the wilderness there is a place where runes drop. it's called darrk warriors fortress. they drop there(water, fire, air, earth...) be careful for warriors(level 9).
in runescape there is many talismans, each create a different pair of runes. not u need to be more specific on this q's. but I'm sure the talisman in the west is body runes.
To make Tele-Tabs you need 7 things: - A House - A Lectern - Clay - Runes for the spell you want made into a tab - Yourself - A staff to reduce need of some runes. - Appropriate Magic Level
Nature Rune is a good source of Exp and cash in Runecrafting, it is the most sort after Rune in the game because mages need it for High-Alchemy, so you best use those if you have the appropriate levels.
