(1) GuideStar does not count as "widely available" because signatures are redacted; and
True, according to the summary of regulations you cite.
(2) Irrespective of internet publication, the Form 990 must be available for inspection and copying at the Organization's place of business during normal business hours.

"The law provides that a non-profit
need not provide copies of its Form 990 or 1023 if it has made those documents "widely available." Under the IRS regulations, an organization can satisfy this requirement by posting the document(s) on the Internet, either on the organization's own Web page, or as part of a database of similar documents, established and maintained by another entity."
