Switching to phones not an option.

Its not like a computer where you can add more ram and replace the cpu to make it faster.
Just get a 3GS or an iphone 4.
With newer and more resource demanding software older hardware cannot keep up to speed with new additions and updated firmware.

Well i bought my phone used and theres something lagging it ever since 3.0 i think the previous user did something to it. NO matter how many times i restored nothing restored it back to its speed compared to my friends 3g. Could something be wrong with the hard drive/ storage capacity thats lagging it or is it just the hardware itself degrading

It depends on alot of things that could cause it to slow down.
Like if its JB and what kind of packages you installed on it. If its stock the more apps and storage you use up the longer it will take to start up and maybe cause a slowdown also.
Like I said why dont you update and get a newer model with non of these issues. Even 3GS iphones are plenty faster than 2G and 3G iphones.

But my question is.. what is left after a restore to factory settings. shouldnt EVERYTHING be wiped so nothing should be sluggish or anything?

Yes, after a restore thru itunes everything is gone as long as you dont restore from backup.
When it asks you after the restore click setup as new.

i do set it up as new but i still feel the same sl;uggishness

Not much more you can do.
It comes with the updated firmware.
If you put it on its original 2.0+ firmware it will fly but obviously with alot less features and non of the appstore apps will work with that version
