Two preflop spots

[emil3000]

Ok, so I am a NLHE player and want to learn Omaha (it's sort of an ongoing project that resumes whenever I run bad at NL). So there's the disclaimer.

Hand 1 $2/4 blinds: I am dealt 89TJds UTG+1. UTG ($180) opens to 14, I call, MP ($936, I cover) raises to 62, SB (covers) coldcalls, UTG calls. So sweet spot obviously but I am not quite sure what the most profitable course of action is, see a flop in a fairly awkward position acting before preflop reraiser or get it in with probably decent equity or a decent overlay. I chose to reraise, good, bad?

Hand 2 3/6 blinds: I am dealt A[img]/images/graemlins/spade.gif[/img]K [img]/images/graemlins/heart.gif[/img]T [img]/images/graemlins/heart.gif[/img]3 [img]/images/graemlins/spade.gif[/img]. CO ($741) opens 21 I (cover) reraises to 72. BB ($795) coldcalls, he seems decent. CO reraises to 270. Can I call here? Is the first reraise ok?
