Bike Advice

I'm not an expert, but I'll offer the following considerations.

You are getting close to the race - in line with the old adage of "Nothing new on race day", this is getting pretty close to race day with regard to considering a new/different bike.  I'd stick with your current one, and consider putting clipless pedals on it.  You have some time to get used to those, and if they aren't comfortable, just swap 'em back out.  Plus, you can then put those on your new bike whenever you get it (new road/tri bikes don't typically come with pedals) - so it's a good investment either way.

Tri or road? Wait till completing your first tri, and then decide.  A disadvantage to tri bikes is that they are not easy to ride in a group with, so if you do a lot of group riding, that's a consideration. However, if triathlons are going to be your primary cycling focus, then go for a tri bike.  As they say, "Don't bring a knife to the gunfight"  

All just my $0.02 - I'm sure others will have more advice soon...
