Pf raising and Continuation bet?
 

Hello,
I play 1/2$ blinds 100$ NL at sycuan b&m casino. most games have Oponents that range from inexperienced players that call too much to solid-agressive types.
Generaly, PF i raise with a-j, a-q, a-k, kq, and pket 9s+ from any position, and in late position if only 0-2 limpers a-10, k-j as well.
Couple questions:
1) as standard am i being too lose raising with a-j/k-q from early position?
2)Considering the small stack size relative to blinds, should i be making it 7-8 when i raise (almost always get callers) or like 10-12 to narrow field? I like being consistent by almost always raising the same amount to prevent reads so id liek to choose 1 option and stick with it.
3)If there are 1-3 players on flop with me after i raise PF i usually CB if its checked to me (hit or not). The bet is between 3/4 pot and pot, is that a generaly sound strategy and good size to bet?
4) Are my CBs goign to be more sucesful if i bet into face cards i didnt pair or ragged flopes?
