Shifter Stuck/bulb question

I purchased a 2001 Tacoma last week. I was working night shift at the time, so that's when I noticed some of the bulbs behind the HVAC controls were out. I figured ok, that should be an easy fix, I assemble cars for a career. Then, I talk myself into changing the lights behind the cluster and at the time I wasn't sure if the shift indicator had a bad bulb behind it or had any illumination at all.
I then found myself ordering a radio so I have something with Bluetooth. So I went from changing HVAC lights to a little bit more projects.
I ordered some Partsam

$9 T10 194 LED Bulbs Blue Super Bright New 5th Generation, T10 LED Bulbs, 168 Bulb for Car Interior Door Courtesy Dome Map License Plate Lights W5W 2825, Pack of 10

T10 194 LED Light bulbs(pictured below). I saw on a website 194 would be the size for all the ones I wanted to do. Guess I should have double checked, because these were to big for behind the HVAC but worked perfect for the cluster. I end up looking under the shift indicator to see if there was a bulb to replace but there wasn't one and so I ended up getting my new radio installed. So 2/3 things completed, not a bad day.
So my first question is:
No auto store in town could tell me what size bulb it is. I have read anywhere from #194 to #74. Is there a recommended site to order these from? And do they come in a green color or just white?
Second question:
I get everything back together last night, I check the lights, everything seems fine. Until I attempt to leave for work this morning. It will not shift out park. Even when trying to use the shift lock, it still will not leave park. So, I decide I'll look at this after work, I'll take the other car. Now I can't remove the keys, like it isn't really in park now. So I push the shifter up some and finally I can turn the car off. I haven't had much time to look at it, so really I'm looking for suggestions on what it could be. Searching through the forum I know to check to make sure the brake lights are working which might indicate a bad fuse. I'm hoping it's a connection I didn't make or maybe something actually stuck in there physically preventing me from moving the shifter. Also, is there a good website that maybe has diagrams of the shifter? I thought I could pull up the actual parts on my works data base but I don't have access to that model year. Thanks for any info!
