And hangs the earth on nothing.

When He inscribed a circle on the face of the deep,

Have you seen photo's of the earth taken from space? The earth is a circle.
As to the genealogies; if you took the time to read what I posted your explanations are found. However,
In Mattew, where unquestionably we have the genealogy of Joseph, we are told (1:16) that Joseph was the son of Jacob. In what sense, then, could he be called in Luke "the son of Heli"? He could not be by natural generation the son both of Jacob and Heli. But in Luke it is not said that Heli begat jospeh, so that the natural explanation is that Joseph was the son-in-law of Heli, who was, like himself a descendant of David. That he should in that case be called "son of Heli" (son is not in the Greek, but rightly supplied by the translators) would be in accord with Jewish usage. (cf 1 Sam 24:16). The conclusion is therefore inevitable that in Luke we have Mary's genealogy; and Joseph was "son of Heli" because espoused to Heli's daughter. The genealogy of Luke is Mary's, who father Heli, was descended from David.
From note on Luke 3:23 Scofield Reference Edition KJV)
Onegod, the Bible is clear we are saved by grace through faith in Jesus Christ. The reference you posted from Romans is dealing with the Torah, (we are not saved by works of the Law Romans 3:28 ). However Paul goes on in Ephesians to state this:
Eph 2:10
10 For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them. NAS
What are good works? This has nothing to do with not working on the Sabbath, not eating pork, not planting multiple crops in the same field, not wearing clothes of mixed fibers; but has everything to do with "loving your neighbor as yourself". James is teaching the same principle. However, James is more pragmatic and direct and states the faith without works is dead. Or to put in more plainly, any man or woman who claims a faith in Christ and does not feed the poor, minister to the sick, etc. does not have a true faith in Christ.
Genesis 33:19-20
19 And he bought the piece of land where he had pitched his tent from the hand of the sons of Hamor, Shechem's father, for one hundred pieces of money. 20 Then he erected there an altar, and called it El-Elohe-Israel.
NAS
Acts 7:16
16 And were carried over into Sychem, and laid in the sepulchre that Abraham bought for a sum of money of the sons of Emmor the father of Sychem. KJV
Acts 7:16
16 "And from there they were removed to Shechem, and laid in the tomb which Abraham had purchased for a sum of money from the sons of Hamor in Shechem. NAS
MACHPELAH
(mak-pe'-la) (ha-makhpelah, "the Machpelah"; to diploun, "the double"): The name of a piece of ground and of a cave purchased by Abraham as a place of sepulcher. The word is supposed to mean "double" and refers to the condition of the cave. It is translated "double cave" (to diploun spelaion) in the Septuagint in Gen 23:17. The name is applied to the ground in Gen 23:19; 49:30; 50:13, and to the cave in Gen 23:9; 25:9. In Gen 23:17 we have the phrase "the field of Ephron, which was in (the) Machpelah."
1. Scriptural Data: The cave belonged to Ephron the Hittite, the son of Zohar, from whom Abraham purchased it for 400 shekels of silver (Gen 23:8-16). It is described as "before," i.e. "to the East of" Mamre (verse 17) which (verse 19) is described as the same as Hebron (see, too, 25:9; 49:30; 50:13). Here were buried Abraham and Sarah, Isaac and Rebecca, Jacob and Leah. (Compare however the curious variant tradition in Acts 7:16, "Shechem" instead of "Hebron.")

As to why Stephen is recorded at stating Shechem (Sychem) in lieu of Machpelah see:
Josh 24:32
32 Now they buried the bones of Joseph, which the sons of Israel brought up from Egypt, at Shechem, in the piece of ground which Jacob had bought from the sons of Hamor the father of Shechem for one hundred pieces of money; and they became the inheritance of Joseph's sons.

You will find some apparent discrepancies in the Gospels, which can be accounted for by the fact you find 4 accounts by 4 unique individuals. The minor differences do not in any way change or detract from Biblical doctrine.
Really, if all you want to do is nit pick locations and minor details this just shows the weakness of your own faith in your religion. If you can't defend your doctrine except by attempting to destroy others beliefs your religion lacks substance.
