I really don't see what benefit a level 34 is going to get from reading anything at EJ. And at level 34 you really shouldn't be DoTing up a bunch of targets. Shadow priests are still going to be pretty squishy at that level. Plus, when it takes less than 5 seconds to kill something, maximizing your rotation is unnecessary.
@OP: It looks like you have the basics down. Open with SWP, then use MF. I wouldn't even worry about Mind Blast at your level tbh, but yeah finishing with SWD is a good plan, especially if you have the spirit tap and SWD glyphs. Although honestly, below you get into the 50's shadow is a major pain to level with. Stuff dies too quick, and you use too much mana too quickly. I would recommend going disc until you get into the mid 50's. Disc is a lot of fun to level as, because you do good dps for soloing, and you can heal really easily in dungeons with fast queue times. It's what I did when I leveled back in February and March. This
is the spec and glyphs you should use. As far as a rotation goes, open with holy fire, cast a couple smites and finish with penance. If you're fighting against a tough mob, or are running low on mana, pop Archangel. You will literally never run out of mana. And I don't use literally lightly. I do like alliteration however.
