1: rock fossils can not be dated with any reliable technique. Only real bone or living tissue can be dated with radio carbon.
2: most accurate technique to date is tree ring dating...
5: skull fossils have either shown to be human, ape or fakes (combinations of both spliced together to support evolution)
(Your point 5 is so ridiculous I will ignore it.)
I will address your information on radiocarbon dating, as that is something I do a lot of.
In point 1, you can also date shell, and a host of other items. The only requirement is that it contains carbon.
In point 2, you mention tree ring dating. That is a very good method, as you note. However, are you aware that radiocarbon dating is calibrated in reference to tree rings? They have gone past 12,600 years or so dating the tree rings every ten years, and creating a calibration curve to account for the small variations in the atmosphere. These variations were noted in either 1957 or 1958, less than ten years after radiocarbon dating was invented.
You supply a link from icr.org. I will take a look, but I tend not to trust any data from creationist websites.
Here are some links I have personally examined and found to be credible:
ReligiousTolerance.org Carbon-14 Dating (C-14): Beliefs of New-Earth CreationistsThe American Scientific Affiliation: Science in Christian Perspective Radiometric Dating: A Christian Perspective by Dr. Roger C. Wiens.
This site, BiblicalChronologist.org has a series of good articles on radiocarbon dating.
Are tree-ring chronologies reliable? (The Biblical Chronologist, Vol. 5, No. 1)

How precise is radiocarbon dating?
Is radiocarbon dating based on assumptions?
Has radiocarbon dating been invalidated by unreasonable results?

You just put your foot in it.
Are you sure of this?
Jenny, you wouldn't happen to have that skull categorization thingy handy, would you?
