Again, conspiracy theories and researchers that don't publish studies. Any number is suspect unless it can be verified by the medical community in double blind research. Without it, we merely have the opinion of a guy.
It's also worth noting that Chadwick, a researcher that worked with Wakefield when he had shifted from mercury to his 'gut' hypothesis, has come forward and repeatedly said the vast majority of MMR inoculated kids show no measles in the gut. Furthermore, false positives are one of the main problems with the "state of the art" techniques used - PCR tests. That's what peer review is for, checking these things.
Your other study merely shows that autism onsets at the same time of life that we vaccinate, but we already knew that.
Again, peer reviewed research is a necessary but not sufficient condition for being taken seriously in science. If you don't have a peer reviewed study to show a link, then there is no link.

Vis-a-vis fetal tissue, this is both true and false. Back in 1966 and 1962 two aborted embryos had some cells cultivated. These cells were used to create a cell line to make bi products MRC-5 and WI-38 that are used in the linked to article's vaccines. Two fetuses, a long time ago. Now I can understand some moral concerns; however consider that the damage from those abortions has already been done, and that by refusing the vaccines you're creating a system that can lead to your, your family's, and many other innocent peoples deaths.
