Yes indeed, lovies; I'd like to go all out and purchase an extremely good synthesizer keyboard, to go along with my Logic software (which I'll be getting quite soon for my birthday! =D Yipee! =D). What does everyone reccommend?

hi!  sounds like it's for you to take a trip to the forums at www.synthzone.com  !  just be carefull!  their a roudy bunch of folks!  but they will give more info than you could possibly use.
the forums can be found in the second block of goodies, listed as discussion pages.

That is a heavily opinionated topic. Everyone has their own idea of what synth is best depending on what type of music you create and how you create it... for example some people do not like workstation synths and just want something with lots of control and great sound but I happen to like the workstation synths especially when it comes to using for live performances. I own a Yamaha CS6x and love the sounds I can get out of it and I like the ability to use it as 16 part multi-timberal instrument with midi sequencing. I would really like to trade up to the new Yamaha Motif line though because everything I didn't like about my CS6x was fixed and upgraded on the Motif series. On the other hand... you got to love the sounds that people are getting out of the Nord synths. I think sound creation on those things is great... for example... Crystal Method use a Nord lead for a lot of their synth sounds and they just keep blowing me away. I also have a fondness for that new Alesis analog monster that came out a year or so ago. Its got a hefty price though. That is my 2 cents ;-)
