Yes and yes.

No - but since 1.1, the carriers have been made stronger,hold more squads and fighters are now more effective vs LRM

Sounds like this game should get some balance issues taken care of. I mean, like the flak frigates aren't even effective from what I’m told, the siege frigates are to expansive for online play, and the caps are powerful with support abilities but they aren't really capital ships as you would think of them in other games, like for example star wars the imperial star destroyer was a nasty thing to have in EAW but in this game there just, as one person put it frosting on a cake. You cant just have frosting for cake.

So basically in the later game my fleet consists of lrms, carriers, repair cruisers, a view cielo cruisers and one or two cap ships? And are Kodiak cruisers effective in online play?, sense there so slow.

not sure balance is the right term. All three races can deploy effective carrier fleets (not read with equal ease)...I pretty much do the same thing, a couple of capitals, carriers, and repair and depending on the opposition the lr grigates may not be needed. Kodiaks are quick easy prey for bombers (as with all heavy cruisers) so I don't like them, as for speed there is a tech upgrade that's addresses the speed and acceleration for kodiaks. The issue with lr frigates is that they're fairly easy meat for fighters, so a heavily weighted carrier fleet carring 65-75% fighters will be pretty tough on lr frigates.
