Roofing Felt Paper Installed upside down..Does it matter?
I finished installing #30 roofing felt paper on my 10x12 shed but after reading around it seems I put the wrong side up 
.. Meaning the lines that were marked on the felt are facing down instead of up. Seems like something minor but do i need to remove it and reinstall it?

Except for the printing as far as I know both sides are identical. I always thought the lines were just cutting aids. Where/who told you there is a right and wrong side?

I was reading here: Which Side of the Tar Paper Goes Toward the Wall? | eHow
but after re-reading they are talking about tar paper, might be different then felt paper

Tar paper and roofing felt are the same. Actually walked out to the garage and my felt is not glossy on either side and while maybe a bit tacky when you unroll it I tested an old scrap and it wasn't tacky on either side but maybe I'm wrong. I can see sticky to seal seams... maybe but it never seemed sticky enough to do that. Maybe heat seals it but I doubt it.

That article is wrong about the sticky side stuff at least as far as I'm concerned. If that were true the rolls would stick together sitting on the pallet in the sun or during transport.
eHow isn't very reliable in my mind.

When I was putting up it was very easy to walk on the side with no lines (spongy with grip). The sides with lines was more smooth. I figured it would be better if the spongy/sticky side was on the shingle side for better grip for the shingles. I just don't want to remove dozens of staples and possible damage the felt If I don't have to

I wouldn't worry about it. The lines make it easier to run your shingles, but a chalk line is just as simple.
As to helping hold the shingles down, or the paper to the roof? Thats what the nails and weight of the shingles does. The only stuff that really adheres to the roof is ice and water membrane.
