      1) The theory is to defend 35% equity vs his range. See the article Pre-flop: Starting Hands and Equity incl. Big Blind Defense (paragraph 10). 3-bets are not covered in the article. General understanding is you need an advantage for a 3-bet, which is at least 50% vs his range. Therefore your passive range is 35-50% vs your opponents range.

      I will not work out all of it in detail but I'll show you a way how you can construct your range.

      First you have to determine your opponents range. According to the preflop article (see 8.1) you can determine the ranges as:

      MP2 = 0.7 * PFR = 0.7 * 27% = 19%
      MP3 = 1 * PFR = 27%
      CO = 1.5 * PFR = 40%
      BU = 2 * PFR = 54%

      which translates to (Equilab)

      MP2 = 66+,A4s+,K9s+,Q9s+,J9s+,T9s,A9o+,KTo+,QTo+
      MP3 = 55+,A2s+,K5s+,Q8s+,J8s+,T8s+,98s,A7o+,K9o+,Q9o+,JTo
      CO = 44+,A2s+,K2s+,Q4s+,J7s+,T7s+,97s+,87s,A3o+,K7o+,Q8o+,J8o+,T8o+
      BU = 33+,A2s+,K2s+,Q2s+,J3s+,T5s+,95s+,86s+,75s+,65s,A2o+,K4o+,Q6o+,J7o+,T7o+,98o,87o

      However these are equilab ranges which don't reflect the playability of the hands and may not accurately represent a LAGs range. I leave the finer details to you.

      After having determined the opponents range you can work out your defending range. You can use Equilab's hand range calculator to do this.

      The result is vs. MP2: 22-77,
      A2s-ATs, K2s-KQs, Q8s+, J8s+, T8s+, 97s+, 86s+, 75s+, 65s, 54s
      A2o-ATo, K6o+, QTo+.

      The other ranges are derived using the same method.

      This range should be finetuned using the heads up playability chart in the thread HeadsUp Playability (download Playability.xls). The chart represents the playability as a bonus to your equity. The goal is to determine the hands which have a combined value of equity + playability = 35 or better.

      So you check the boundaries of the range above:
      A2s >41, A9s <49
      K2s >36, KQs >51, KJs <49
      Q8s >36, Q7s = 34.87
      J8s >36, J7s = 35.14, J6s <34
      T8s > 38, T7s = 35.8, T6s <34
      and so on.

      Your final range would then look like
      22-77, A2s-ATs, K2s-KJs, Q8s+, J7s+, T7s+...

      which is somewhat looser than the chart in How to play short-handed (with charts) but not very much.

      2) The same principles apply. The result of your defending range should be very near the shorthanded chart of the silver article.

      The 3-bet range in SB can be constructed using paragraph 8 and 9 of the Gold preflop article (see above). Basically you need a equity + playability of 48% vs a LAGs range and 46% equity vs a TAGs range. The method is the same as in 1).

      Also, as an alternative, you could in general defend your BB passively if you are alone with the raiser and if the raiser cbets in the majority of cases on the flop after you check to him.
