Preflop, I would raise. you obviously couldnt know that the 4 people to act after you were all going to limp into the hand...but who wouldnt with so many limpers, the odds give you no choice. Your hand is solid, not great, but worth an investment of a raise to 150 imo. but, more importantly, it would go a long way in defining your hand and help you find out who is serious and who is prospecting. investing an extra 100 chips at this stage does so much more for you than waiting until after the flop. moreover, if someone pushes over the top of my raise here, i have no problems laying this hand down and losing my 150 chips.

tough call on the rest of the hand. TPTK has taken down many people in here i am sure...tough hand. But, because you did not protect it by raising preflop, i personally would play TPTK very cautiously...i think i would be in teh same position as you if i played this hand without the preflop raise. i hope TPTK was good!
