I'm thinking of pushing the total up to 6GB by getting an extra 3x1GB in triple channel, as the motherboard has 3 more slots available in a separate "bank".
My question is, do the new sticks have to share clock speeds and timings with my existing ones, can i "underclock" the faster set to match the slower one if they need to match, or do i just plug them in as long as they are in separate banks?

In case of triple and dual channel RAM.. This has got to do with how the chipset addresses RAM and it's bus-width. Dual channel is 2*64bit and Triple 3*64bit bus-width.
For the chipset to be able to address memory like this they have to be identical in terms of not only speed but also model and make etc. The "system" sees the two or three RAM sticks as one bank of RAM memory.
On a X58 you have two sets of triple channel memory slots. That's why the banks have two sets of color coding.
You don't need to match your new set of RAM sticks with your existing ones in terms of make and model.. The new set should be matched though so that you can run them in triple channel as well. The bus can not run individual frequency to the different banks, so all memory must run on the same speed and with the same timings. So your "worst" RAM stick will set the mark for all other..
