1) Shelves should not be removed from or replaced into a bookcase on Shabbos, even if they are not screwed in and simply lay upon pegs or dowels as is common in many bookcases, as they are meant to remain in the bookcase permanently and as such are deemed part of the bookcase.
The aforementioned Halacha applies only to large bookcases or even to smaller bookcases if they are mounted to the floor or the wall, as bookcases that are small (can hold less than the volume of 40 Sa'ah) and are not mounted to the wall or floor may have their [loose fitting, self-standing] shelves removed and replaced (as we shall B'Ezras Hashem discuss more in detail when we discuss Boneh in regards to Keilim, utensils)
2) It is prohibited to hang a curtain or drape onto its track or shaft on Shabbos [if it is to remain there permanently] as doing so is considered adding on to the structure.
If the curtain is only being hung temporarily according to some Poskim it is permitted, while other Poskim prohibit this as well. (See Rama Siman 315:1 and Chazon Ish Orach Chaim Siman 52:13)

Reader's Question:
You mentioned that when one makes hamotzi, all their fingers need to be touching the bread. Is that just for on Shabbos with Lechem Mishna, or is it during the week as well, when eating any bread?
Answer:
This applies anytime bread is eaten, weekday and Shabbos alike.
The reason for this is that there are 10 Mitzvos that are associated with the process of making bread (During the plowing of the field: 1) an ox and a donkey may not be used together, during the planting phase: 2)one may not plant two different species together, During the reaping phase: 3) Leket, 4)Shikcha and 5)Peah, 6) the ox that is used may not be muzzled while working, After the baking phase: 7)Teruma to the Kohen, 8) Ma'aser Rishon to the Levi, 9) Ma'aser Sheini and 10) Challah to the Kohen)
It is for this reason that there are 10 words in the Bracha of Hamotzi and 10 words in each of the Pesukim that refer to the bread of mankind (See Shulchan Aruch Siman 167:4 and Mishna Berura 167:23 ad 24. The verses are: 1) V'Yiten lecha H'Elokim... (Bereishis 27:28) 2) Eretz Chita U'Seora... (Devarim 8:8) 3) Matzmiach chatzir L'Behaima... (Tehillim 104) 4) Einei Kol Ailecha yesabeiru...(Tehillim 145, better known as the psalm of Ashrei)
Some people have a Minhag on Shabbos not to place their fingers directly on the Chalos, rather to place their hands on the Challah cover. However, the prevalent minhag according to most Poskim is to place all 10 fingers on the Chalos, even on Shabbos. (See Mishna Berura 271:41, Shu"t Be'er Moshe Vol. 6 Siman 134 and Sefer Minhag Yisroel Torah Siman 271).
