Meaning no disrespect, some corrections to the first few (to the best of my knowledge; please excuse me if I am wrong):
1) dharaNii-garbha-sambhuutam.
2) ruupeNa-apratimam would be the correct split.
3) I feel that "saumya" in this context might mean "born of sOma" rather than "gentle".
4) himakunda-mRNaala-aabham would be the correct decomposition, mRNaala being the fibrous root.
5) SanaiScaram == SanaiH caram == to him who moves with sloth.
Sincerely,
Varun.
