I would like to do a few mods to my 92 305 TBI, 1st, i want flowmasters, people on this site told me 80 series are great, true?, I want straight pipes also and i do not know size, does anyone know what the outlet size will be from the flowmasters? is that was i need to base it on?, I want a 360 degree air cleaner to replace snorkel setup, there are two wires running intpo the current one, a vacuum line correct? and some other one. Is it possible to have the 360 open element air cleaner and do i need those lines or not?? any help is appreciated

You can put an Open Element on your car, aka 360 air cleaner.

Read snuflupigus's tutorial here http://snflupigus.tripod.com/step1.htm

I'd also suggest going through the Ultimate TBI mods if you want some performance out of your car. just make sure you can tackle this, im not responsible for any mess-ups, don't kill the messenger.

I'm a little confused on what you're asking exactly about the exhaust. I personally don't like flowbastards because they really don't flow as well (or sound in my opinion) as good as all other free flow designs. If you want to go with flowmaster then call up Summit and they'll ask you for your car blah blah and the kit will be sent. If you already have exhaust work done like a larger cat converter or headers, then you'll need a 3" cat-back exhaust system and make sure you tell them that. I personally think the hooker system sounds a lot better than flowmaster, just my opinion. As for the open element (aka 360) air cleaner, Summit sells a $15 piece that includes everything. It's a drop base so you'll need to retain the stock spacer ring (it's imbetween your stock air cleaner and the engine).
About those vacuum lines and that sensor:
You can remove the sensor and simply zip tie it to anywhere on the firewall just as long as it doesn't touch anything hot! It's common to zip tie it to the MAP sensor. As for that vacuum line. Plug both lines or at least the line that goes to the throttle body. That vacuum piece is a thermac sensor that operates your stock air cleaner heat riser POS.

I'm all about my Dynomax cat-back. I've got Dynomax headers/y-pipe, no cat, and the 2.5" cat-back. It sounds right.
