Help With OHMS, Speakers, Reciever

Hello Everyone,
i need some help with setting up the speakers and amplifier/reciever.

Don't know who to contact.. people at the store don't know these technical terms and wasn't any help.

Here's the situation.
i've been using Logitech z5500 speakers for 15+years now....
recently decided to upgrade the whole entertainment section.
and decided to go buy a new receiver as well but will wait about a year for the speakers because don't have proper space/setup for the speakers.

Currently deciding to use the z5500 sattelite speakers as i have 3 sets of 5 speakers

i'll only be using 5.1 setup because of the space...
have the seperate sub-woofer , wont be using the z5500 one.

here are the Specs of speakers .(according to internet)
Left/Right: 62 watts RMS x 2 (into 8 ohms, @ 1khz, @ 10% THD)
Center: 69 watts RMS (into 8 ohms, @ 1kHz, @ 10% THD)
Rear Left & Right: 62 watts RMS x 2 (into 8 ohms, @ 1kHz, @ 10% THD)

Here's the specs of Denon S960H :
- 90W per channel (8 ohms, 20Hz-20kHz, THD: 0.08%, 2 channel driven.
- receiver can handle 4-16Ohms
- Doesn't support Bi-amping.

My question is :

-since i have so many sattelite speakers laying around.... Can i connect two speakers to each channel.
- which would be better Parallel or Series
- if its too much power can i connect atleast center channel x2 .,. since i'm sitting 20ft from the center channel and right underneath the back speakers

i know i can change the level of the speakers to be less loud and more loud.but i would prefer connecting more speakers...
i know i can connect it and they will work ... either in parallel or series but i want to make sure i don't want to blow up anything specially the receiver ...speakers are ok because i'll eventually change them... :-D

Please if someone can help me on this topic. who have an idea about Speakers, amps and all the other things.

Thanks for taking your time to read and reply.
P.S. : if you find lots of spelling mistakes in my above comment. This is what happens when you use the physical Keyboard (Blackberry) your whole life and then you have to settle with a virtual Keyboard.

Multiple speakers on a channel are normally connected in parallel. The impedance in that case will be half if two speakers in parallel are the same (e.g., two 8-ohm speakers in parallel make 4 ohms).It's not recommended to pair different speakers in parallel,

Keep in mind that the rated impedance is the approximate minimum of a value that varies widely across the frequency spectrum. It's not uncommon for an 8 ohm rated speaker to dip to 4 ohms in a narrow band around its resonant frequency. This could be a problem when connecting speakers in parallel, but normally if the manufacturer has rated conservatively, and you don't push things too far by using max volume, it should be ok. By the same token an amp rated to drive a 4-ohm load can usually withstand a lower-impedance load briefly - if the current draw and resulting heat produced in the output stage spike very briefly above the sustained max rating, it probably won't cause an instant failure. But no point in pushing things.
