Troy, the C/F tape for the spars can be had at a number of places. All you need is .007" strips. Just CA them to the one side of the spar, and that side faces outward on both top and bottom.

The wing tube is actually very simple. From front to rear alignment, just line it up with the plans. If you have to sand and tweak a rib or 2 to get it right, that's fine.

The alignment vertically is done by building the wing upside down (top touching the building surface) and use a level on the tube. IE install the tube in the sicket and use a level to check your table first, then the level of the tube. it should be the same. For what it's worth, if you cut the holes in the right place, in my own experience I've never had one even slightly off vertically. From front to back it may move a little but this is usually due to the spar slots and you can just sand those to fit.

Glueing depends entirely on how good you fit is in the rib. I always use epoxy on the last rib and between the spars (the spars will interfere a little so use a wing tube with a piece of sandpaper to get this to sit down correctly). If the rest fit snugly, just use some thick CA. Leave the root loose as you will need to install the wing on the plane and align and glue the center tube first, then use the curve of teh fuse to set the proper root rib position. Just tack glue some small 1/4" pieces to the root rib and tack those to the fuse. When the wing is perfectly aligned, glue the root rib to the spars and the bottom sheeting. Then cut the temporary blocks loose and install the upper sheeting.

I hope that helps, let me know if you have anymore questions.
