Terminology for beads/necklace/bracelet problem
MO is for "research level" mathematics, and MSE is for mathematics of all levels. Of course, it's open to interpretation what "research level" means (and it certainly means different things to different people). Anyway, lots of very competent mathematicians answer questions at MSE, and questions such as yours might get a better reception there. (Although it looks like you might already have an answer here).

Terminology for beads/necklace/bracelet problem
What you are doing is enumerating the cosets $\Sigma_N/H$, where $\Sigma_N$ is the group of permutations on $N$ letters and $H$ is the subgroup generated by cyclic permutations and reflection. I don't know of a name for this. (I also think this question would be a better fit for math.stackexchange.com.)

Connected representant of a framed cobordism class (reference needed)
Ah, OK. Where does your proposed proof for $n>0$ break down when $n=0$?

Splitting the Hopf map in two
Note that there is nothing special about the Hopf map here. Any map $h: S^3\to S^2$ is nullhomotopic when restricted to the equator, since the inclusion $S^2\hookrightarrow S^3$ is nullhomotopic. So there will be a map $h':S^3\vee S^3\to S^2$ which expresses $h$ as a sum. In general, though, $h'$ will depend on the nullhomotopy. Choosing either of the standard nullhomotopies will no doubt result in one of $f$ or $g$ being null and the other being $h$.

Milnor's exact sequence and a certain proof
Regarding the description of the connecting map $d$: my coauthors and I needed this and couldn't find a reference, so wrote out "actual argument" in our preprint arxiv.org/abs/1312.7166 (it's the $n=2$ case of Proposition 2.1 there).

Topological relationships between family of transversal intersections of manifolds
Oscar beat me to it by a few minutes, but I thought I'd post the answer anyway in case you find the references useful.

Proof or citation?
Maybe you could include a sentence or two explaining why it is trivial? That way you can help your readers reconstruct the proof, without appearing patronizing.
