System Specs are fully updated.

Link to PDF of System Specs from specific model from Toshiba.com.

I need to add RAM. It currently has 4GB, but it isn't sufficient. I have to use VMWare workstation, Microsoft Office, Google Chrome, and possibly Microsoft Project, and other high resource software.

It says both slots are occupied (I am guessing 2GB per slot).

How difficult is it to replace? Is it worth it?

Average cost? Can you recommend one? Ideally, 6GB-8GB is desirable. I don't have much to spend.

I am an Information Systems student (for tech knowledge).

It would be nice to find the motherboard manual. It would give needed information.
I Googled and all I got was a bunch of eBay stuff and some chop stick websites.

I had the same issue. Access to the System Board (which was defective and Toshiba had to replace it) requires pulling out the processor. I couldn't find the manual either :/

It says right here in the pdf you posted, did you even read it ?

Memory
 Configured with 4GB DDR3 1066MHz (max 8GB)
 2 main memory slots accessible from the bottom. Both slots occupied.

Is it worth it ? Of course it is, max it out to 8 GB :)
How difficult is it to replace? A child could do it :)

You can purchase it at your local Bestbuy. You`d want 2 of these.

If I can only afford to buy 1 of these, is it advisable to upgrade to 6GB of RAM (2GB OEM in one Slot, 4GB in another)?
OEM was Samsung, New would be PNY.

The Laptop is about 5 years old. What are you guy's thoughts. Should I bite the bullet and stay on this PC and is 6GB of RAM even sufficient or compatible? or wait until around January-Feb of 2016 when things get smoothed out and hardware advances are made 6 months after RTM of Windows 10?

Either is an option at this point.

Anyone on the 6GB of RAM compatibility question?

(OEM 2GB in 1 Slot (Samsung), Add new 4GB RAM in other slot (PNY)

I found the following additional information which is as specific as it gets:
AMD Turion II Dual-Core Mobile M540 - TMM540DBO22GQ


Thanks!

Is it necessary for it to be 1066mhz? I am not super familiar w the Mhz w/ the exception of electrical input. Additionally, why is it so hard to find additional info on this Motherboard ard (It was defective and replaced by Toshiba during warranty period). My battery is also failing. Things are getting expensive on a 5 y/o laptop.

It seems easiest to find 1600mhz RAM, however that is higher in Mhz.

I do have an Amazon gift card....

Their supplemental parts in the manual are listed to buy original Toshiba replacements. It says: PA3677U-1M4G Toshiba 4GB DDR3-1066 Memory Module

A 1600 MHz RAM stick will run just fine at 1066 MHz, as long as it's the same kind of memory. For your machine it must be DDR3, which won't be a problem.

But yes, you can safely run a 1600 stick at 1066. No harm will be done.
