This should really be in the Hardware thread, but ... the mods are not looking very close.
They say a picture is worth a thousand words.

Wrapping Coil on SS Mesh Wick - a set on Flickr
(It's incomplete as I didn't stop to take stills as I was rolling the Stainless Steel mesh and wrapping the coil.)
I probably went overboard on the needle nose pliers, but I work with electronic/computers a lot and you never know what you'll run into. One good pair of needle nose is fine for this job though.
A good pair of wire cutters (or nail clippers) work well on both the wire and the silica. (and rolled mesh, scissors for flat sheet)
A straight pin or two. One for supporting the silica as you wrap the coil and one for tweeking the wire to make sure it's spaced evenly and not over lapping anywhere.
I used a straightened out paper clip to support the wick. Also used if rolling SS mesh.
My mini screw driver set, bought before vaping, has philips head, flat head and Torx (six-pointed star) which you won't need but some atty's use sexkant (allen head) screws so it's good to have a small allen wrench set handy if they don't put one in the package.
Tissue paper or paper towels for wiping up juice.
On my T3 atty head, which is almost the same as Protanks and Evods and vary similar to ViVi nova heads, I used 2.5 mm silica in place of the 1 mm original wick (at least it looks like 1mm). One strand for the coil and 1 1/2 to 2 strands laid on top for extra wicking.
I think, I used A-1 32g Kanthal wire for the T3 coil and wrapped a 6/5 coil. The bag of wire wasn't marked, duh, so it may have been 30g wire. Anyway, it's reading 1.9 ohm.
A couple tutorials: just in case you haven't seen them already.

Good luck with rebuilding. Frantic9k. Let us know how it goes and come on over to the Hardware Thread and check it out.
EDIT: Ok, I just got done watching both those videos and both had some really good points in them, however, there were a couple things I would have done different.
Basilray didn't show how to wrap the wick around the coil; he wrapped it off camera and brought it in when he needed it. Not to cool if you've never wrapped a coil before.
GrimmGreen, again for the most part, fine video. The one section I didn't like was when he trimmed the coil wires. I believe it's better to leave them long until you have the robber grommet and the center pin back in place. The reason here is when you have that extra wire folded down over the edge, you can hold it in place under your finger while putting first the grommet and then the center without fear that either component is going to push the wire back into the whole, which pushes the coil up out of place. It happened to the T3 head I rebuilt - luckily I could grab the wire and gently snug the coil back down into the notch.
That said, I found this video:

This third video is a good one also; it has more detail in wrapping the coil, better method of inserting the grommet and pin, but still there is something else that bothered me about this one. When Snaredrummmer88 does the dry burn he cranks the voltage up to max! Good way to pop your coil there!
I always start at the lowest voltage setting and gradually work my way up and holding the fire button down for a couple seconds at a time.
I also don't think you need to soak the coil/wick before vaping. I'd just rinse out everything before starting the build.
And personally, now that I'm getting more practice, I think my coils are better than the stock ones. 
Just going by what I've heard, seen and read other people doing mainly.
