"1. So, assuming I have a developing L-H-O home sector, am in a 1-member corp, and have a loaded ISS and a loaded Sentinel at my disposal, what's the best way to sleep? Jump in the Sentinel and deploy my ISS fighters to the sector pool? By "best" I am thinking more about protecting my assets than anything else."
well, i will assume this is pure stock... L-H-O is a rather old way to go... again, i suggest reading
http://www.tw-cabal.com and learning some of the new tactics. as for stock sentinal. i'd rather sit in an ISS than a stock tholian, as it will take more figs to take a loaded ISS than a loaded stock tholian. however if you have a lvl2+ cit, the figs are FAR better on the planet. but i wouldnt sleep on a planet unless it has shields and a whole boat load or ore and figs.
"1b. How does the answer change if photons are currently disabled by the sysop (temporary)? "
not at all really. in stock, if you arent going to be online, figs are best on the planet.
"2. At what point to do you generally feel safe as a Blue sleeping in your citadel (assuming a modest # of players and no powerful corps, yet)?"
when it is uninvadable
"3. So is there any advantage at all to having high exp as a Blue other than showing off your rank and being able to kill just about any other Blue and survive the alignment hit?"
experience and alignment are different.
there is no advantage at ALL for a blue to have high XP. (yes, up to 1k xp ship haggles are better, BUT, red's get the same advantage, so to be blue, is moot in that aspect) and you take an alignment hit compared to how many figs you use and how much align he has and if you pod/#sd# them. again,
http://www.tw-cabal.com can answer this question very very well for you.
"4. What happens if my aligment dips below 1000 while in an ISS?"
from 0-999 i dont think anything happens
when you go -1 and below zyrain gets all up in your isht. heh.
refer to
http://www.tw-cabal.com for theories on how hard you can push zyrain.
"5. With a commission, can I always twarp to fedspace safely no matter how many objects are in it (assuming no nav haz)?"
with a commision and a twarp and holds full of ore, you can *always* twarp to sectors 1-10 and SD with no problems. there *can* be haz in sectors 2-10. and if you hit the haz, and dont have the shields/figs to take the hit, then u get a nice pod

and if you hit it and have a photon, u lose your turns

but, you *can* twarp there
