So, what tranny fluid do you guys recommend? I have been reading up all I can but im just getting confused. People are saying redline or royal purple, and then they argue over g-5 and g-4 ... I dont know what is what, so could someone tell me an exact model of number that will be the best for my worn tranny. I think .... its got some regular like .... generic brand like car quest crap in there. :0( I hope thats the reason im grinding second and 5th.

As for fluid, don't use GL5, it's bad for synchros. I've read a very good review of NEO fluid (Mazdatrix carries it). The guy used it back to back with Redline MT90 and found it to be much better. The Redline MT90 is also a very good fluid and is a big improvement over converntional fluids.

There is a significant gap in ratio between 1st and 2nd gear that is inherent in all 2nd gen transmissions. If you shift into 2nd at redline, you will be greeted by a grind almost every time.
It's the price you pay to play the game. Either be more gentle on the transmission, or deal with accelerated wear.

If you want to learn how to drive stick better, I believe that you need to know how the parts work. That way you can identify good use and bad use.
I usually goto How Stuff Works to learn about things. They always have nice pictures and animations. And they have a huge automotive section.
http://www.howstuffworks.com/transmission.htm
All transmissions have dog teeth. It's the synco that puts the collar and teeth in sync (get why it's called a synco?) s.t. they line up properly. Or at least they should all have teeth. The new ones may just use syncros.
Anyways, this is why good tranny fluid is so important. Just like a viscous clutch in the fans, or a Viscous LSD, fluid helps the process along more than you think. It's not just to lube the moving parts, it's to help engage them as well. That's why you put 75W90 in a tranny.
If you ever think of matching revs, you're going to be double clutching. Easy to learn. Damned hard to master. I've seen truckers who've been driving for a few years mess up double clutching terribly. And they probably get just a little more practice than you do over those years
God help the automatic tractor trailer transmissions.
Honestly though, I beleive the best way to learn good driving habits is to watch someone else. I think retired truckers should teach driving school to be honest. Oh but not the burnt out ones ... oh god that would be problem. I don't think a single woman would pass drivers ed... they'd be crying too much... as well as a few good men...

No, as of right now I Cant downshift into second for any reason. I know first has always been hard (had to almost be stopped) but just recently it doesnt want to downshift into second even when going under 20 mph. *shrug*

Try giving it a little throttle while you downshift (make the RPM 1K while you shift)... that should help.
Also, try synthetic gear lube.
Not being able to go into first without basically stopping is pretty much normal.

Pilot Bearing
I started to develop problems with shifting. I have a TII tranny behind a hybred turbo 13B Cosmo with a mild street port.
At times it wouldn't come out of gear at stop signs and it would die. Then it didn't want to go into gear when I restarted the engine in nutral.
Right now, the shop is trying to remove a chewed-up pilot bearing. Then the tranny goes to have the shaft checked. Can't wate to get it back to feel the difference.

Well, I called my dad who helped me install my tranny this last time, and he said that we replaced both the pilot and throw out bearings. So I gues it isnt that. Unless .... we did it wrong... but I'm going to try replacing the tranny fluid today. My dad said we put in some cheap G-5 stuff and might not have filled it up all the way. *glad he remembers this now... haha*
I will keep you guys posted.
