After reading the section on the 1893 planter "revolt" in hawaii and the eventual annexation of hawaii in 1898, do you see any similarities between these events and the way that texas and california came into the union

The presence of Anglos was the similarity--Anglo (white) people in the regions held economic interests leading to the revolts against the leadership and a demand for annexation. 

After the Mexican Revolution, the whites living in Texas, who also were the main ranchers of the region, asked the US to assist in a revolution against Mexico to become independent. The independent nation requested the US to annex the state so the whites could regain connection to the US. During the Mexican-American War, the region of California also staged a revolt against Mexico and declared themselves a free republic called the Bear Flag Republic. The white settlers in the region assisted the US with the war and after became part of US territory. This is the same as Hawaii, white land owners and farmers asked the US to assist in a revolt and eventual annexation of the islands. This put whites in power in Hawaii to control the territory.
