Now what is seeming to happen is that when first driving the car, when i get into it in the morning or after i haven't driven it for several hours, when I shift from 1st to 2nd it feels like there is alittle bit of grinding. Its not enough to keep my from shifting it into gear or its not loud or obnoxious, I can just feel it through the shifter handle. Thats the only gear that it does it in and it will only do it maybe once or twice and it doesn't happen if i bring the rpm's up to about 2500 or higher before I shift. Its really strange to me. Now, I don't know if this is really connected to the work that I did to the car because I don't remember feeling this at all for several days after I finished the installs.
Could I maybe have not put enough tranny fluid in or messed up one of my synchros somehow?

If your problem is related to the shifter or a synchro, I can't help you. But you say it only does it when the car is cold or hasn't been driven in several hours. Makes me wonder if you put enough trans fluid in it and it's taking longer to lubricate everything when it's cold.
How much trans fluid did you put in? It needs 4.6 quarts. To get 4.6 qts back into the trans using the driver's side fill plug, you need to jack the driver's side of the car way up--and I mean WAY up. The other and probably better option is to remove the reverse sensor plug on the passenger side of the trans and fill it there. You have to measure the fluid, you can't rely on "it's full when it runs out the fill plug".
