Here is the feedback to your issues:
"On the R.o.C page the "Read More" link is broken, took me to the 'Storage' forum" - I think you mean it took you to the forum where it says "More about - Read" this is a bug. Its supposed to show more about the subject, but only to non-logged in users. For some reason it thinks the subject is "Read" instead of "read more"
Typos - Will be fixed
"I had over 150 best answers in the graphic section and a gold badge! WTF happened?" - very important point: part of the beta is to ensure that all of this is migrated correctly to the new system. In this case, you have been granted the "Graphics veteran++ (Legacy)" badge that requires at least 150 best answers. New badges are based on the new tagging system, and the new "Graphics cards" badge will be granted based on best answers to threads tagged "Graphics cards". For now, the thread tagging has been roughly applied, so that there are both "graphics card" and "graphics cards" found in the forums. When everything is more consistent (everyting tagged "graphics cards"), more relevant badge levels should be found.This is though a time-consuming task, so give us some time to conduct this tag consistency job.

"No limitation on signature size" - at this stage we leave it to the mods to act on signature abuse.
"I also cannot lose that pesky sidebar." - it cannot be removed at this stage. We are going to add this feature back, but its going to take some time, it won't be done by the initial release. More like 2013, unfortunately. We need to think of the best way to do it.
"Who OK'd the Smiley list?" - it has not been reviewed by Joe yet. Any input welcome. Or even if some people would take charge of reviewing this list, that would alleviate Joe's work. Key points: do not add more than 5 smilie icons to this list. Change smilie codes as sounds good. Remove unnecessary smilies.
