These questions (as stated) really have no specific answer.
Consider the first question:
For one, important information about the bidding system you are playing, and the opponents are playing is completely missing. The scoring and vulnerability are also missing.
Even if the above information was specified, then giving a specific hand and asking if it is a takeout double or should partner pass it or not (without even giving partner's hand) is not really an objective question and is too localized.
If the question was rephrased as: opps playing blah, us playing blah, scoring blah etc in the sequence (1H) - Pass - (2H) - Double, is the Double for takeout? Then such questions might be ok (but still are borderline localized) and IMO actually bad questions as they show no prior research: this is just checking what the system defines it/you and your partner have agreed. If neither, then it is a gray area and has no real objective answer.
If all the question asked was if partner is a passed hand, will your double be takeout (without providing a specific sequence {based on the title of the question}), then it is either a "lookup your system" answer or cannot be answered objectively ("it depends").
Consider the second question:
(Note that system/scoring/vulnerability was also not provided)
If the question was just: "do you count points in opponents suit when making a takeout double?" The answer is "it depends" or "when the hand calls for it".
If OP is interested in a specific situation (giving a specific hand) then it is too localized.
This is not a my partner is nuts/assess the blame site. Questions which ask what one should/should not have done probably needs to be closed. I would recommend OP ask the questions here: http://www.bridgebase.com/forums/index.php
