I can probably reply most of the logistic questions.
1. For those of you trying to maximize your UA metal miles before the rules change starting 3/1, your options are US/NRT, US/HKG, HKG/SIN, NRT/SIN as well as sCO flights out of GUM. There's also HKG/SGN. You may also look at NH flights out of NRT and I think HND that are code share UA - not sure if they need to be on 016 ticket stock or not in order to get full PQD/PQM per the old rules.
2. If you transit in NRT, it's not clear to me if you can get the BP for the return flight (SIN/NRT, and NRT to wherever you're going afterwards). This may not be available until the following day no matter what.
2. In SIN, UA flights go into and out of Terminal 3. The available lounges are three: SATS, KrisGold (SQ), and Silver Kris (SQ). All three lounges are in a row one level up from the departures level via an open escalator right after passport control and are open 24 hours. They are all departure lounges, not arrival.
... SATS is the UA contract lounge. You need a pass to enter (obtained at check in or from transit desk on airside). Pass goes to F, C boarding passes, and to *G status holders (if you're UA MP, that's Premier Gold and above).
... If you have a *G card (not just UA MP, but also high/er status members of other * Alliance carriers) and UA boarding pass you can also enter one of the two SQ lounges. Kris Gold if your UA flight is in Y class; only F or C class BP allows entry to Silver Kris lounge. MP general member, silver unfortunately no entry. Also, no boarding pass, no entry.
... You can double up SATS entry with either of SQ SKL or KrisGold.
... SATS and Silver Kris have showers, Kris Gold does not.
3. Departure and arrival at SIN are co-mingled. If you can't get UA boarding pass before or on arrival, then only place to get shower upon arrival is at the Ambassador Transit hotel, better to make reservation. Not sure if the other pay lounges have showers. In case of need, there's a transit hotel at each terminal (T1 and T2, aside from T3). There's an airside airtrain so you can get around. Alternatively there are plenty of places airside where you can catch a few zzz's before taking the flight back.
