Mooh is absolutely right. To convert a right-handed guitar to left-handed, you need to get a new nut (with the "fat" and "skinny" slots reversed), and reverse the angle of the bridge saddle (giving you a slightly longer scale for the bass strings). Get somebody competent to do this stuff for you; you can really screw up an instrument by taking on a job like this without really having a handle on it.

As for recording, generally small guitars tend to be easier to deal with than big guitars. But the best advice I can offer is to use an instrument that allows you to play your best, and do a lot of experimenting with microphone positions so as to capture a good balanced tone. There are lots of options, and a number of articles out there these days providing information on what sorts of results you're likely to get with different microphone types and positions (the home recording revolution is prompting a lot of "how to" articles for relative laypersons). Do some homework, and a lot of comparative listening. Good luck.
