a) I play regular old Stayman and 4-way transfers, nothing very special there. However, if you want a comprehensive and very good system over 1NT there is a system called 'Heeman' (an alternative to Stayman developed by Wim Heemskerk, based on ideas of Lindkvist, Nilsland, Wirgren ("Notrump bidding -the Scanian way") and the Italian player Leandro Burgay. Unfortunately my only sources are in Dutch). I know one very strong pair at my local club that play this, and my partner flat out refuses due to the complexity (and he's probably right). In this system it is possible to show mild SI with 6(+) in a minor suit on the following, entirely artificial, auction:
1NT - 2♣* (forces 2♦);
2♦* (forced) - 2♠* (either (54)+ in the minors, invitational(+), or 6(+) in a minor, SI);
2NT(min)(/3♣/3♦ natural, non-min, better minor)-3NT(to play opposite min hence mild SI with a minor suit)/(3♥ 6(+) clubs and SI opposite a min/3♠ 6(+) diamonds and SI opposite a min).
b) To be honest I would not be able to bid this slam at the table, we'd just bid 1NT-3NT. To properly evaluate the West hand I would count my modified losing trick count out of habit (8, yikes. Although ♥Qx may not be wasted) and then try to imagine what sort of minimum would give slam play. As a general rule it is wise to make a slam try only if a suitable minimum would make it good (some say 'cold' instead of 'good'). Since partner has no shortness we have problems in all four suits. I invite you to come up with a more fitting 15-point NT hand than the one shown, the best I could come up with is swapping the hearts and the spades. And even opposite the near-perfect East hand shown you need to find the jack of spades or have them drop 3-3 to make 6♣ on a diamond lead, as well as find the trumps 2-2 (however, if the clubs break 3-1 3NT is also down on a diamond lead). I would simply bid 1NT-3NT without a hint of slam, and would do the same playing Heeman.
c) I've only got two big tips for points versus loser counting. The first is that all of these counting schemes are only tools to help you make your decision, and give a general suggestion of whether you should be bidding more or less aggressively. I think it was one of Reese's books that said that there is no substitute for "imagining the hand partner may have, counting the tricks you have opposite that hand and bidding accordingly". If you combine this with the advice that you are worth a slam try only if it has a good chance of making opposite a suitable minimum (I think this gem dates back to Culbertson?) it should warn you not to make a slam try with the West hand (and if it makes anyway, tough luck). Furthermore asking for support in minors oppposite 1NT is awkward anyway, so even if partner has that 'suitable minimum' you may not get to slam (or you might end up in slam opposite a non-suitable hand).
The second tip is that I really do like a version of the MLT for high level (5+) suit contracts. Assign 1.5 to each missing ace, 1 to a king, 0.5 to a queen, capped at the length of each suit (so ♥Qx is 2.5, missing both ace and king, and ♥xx would also be 2.5, because the queen only counts in suits of length 3 and up). Again, it is not a substitute for bidding judgement, but can be a helpful tool to decide.
d) Over a weak (12-14) NT I play 2-way Stayman, and this hand would again just blast 1NT-3NT. There exist sophisticated relay methods over 2♦ artifical GF that are particularly useful over a weak NT, but I don't play them.
At pairs (matchpoints, right?) you 'never' want to play 5m - you quite literally only try for 5m if 3NT is out of the picture. My old partner used to joke that 5m at pairs was forcing to 6m. If partner opens 1NT (weak or strong, doesn't matter with this particular West hand) 3NT is very much in the picture so I wouldn't even dream of anything else.
