I live in Fort Collins and have hunted theses units for 5 years for both deer and elk. That is great you have a contact that knows the area, hopefully the deer and elk as well. GENERALLY SPEAKING 191 is a deer unit because of the habitat and 19 is a elk unit, again that is a genereal rule of thumb and not to mean there is no elk in 191 or vice versa.
You are correct on getting a tag, it is easy, if you wanted you could buy a tag at wal mart the day before the season opened, there is simply a lot of leftover tags for this area.
PAcking in (or simply getting away from any road a mile or 2) is an excellent idea and I would recommend it.
I am a fan of the later seasons 3rd and 4th (mostly weather and bucks start rutting) so I would say go for 3rd and maybe consider 4th.
HUnting unit 19 is interesting. From Cameron pass your 1st access is Long draw rd, a little further east is Pingree park road which has crown point rd splitting off of it, next is stove prairie road. These roads provide most of the access into the unit and therefore have most of the pressure. You can try to park along highway 14 and go in or the buckhorn road on the south side of the unit. Hunting 19 is tough because most of the unit is dark heavy timber and the elk population is mediocre. Success rates are in the single digits for unit 19 for pretty much every season and only about 10-12% in the late cow (Nov/dec/jan) seasons! Often I ask myself why I still hunt in unit 19? Well mostly it is convience and familiarity. I bowhunt elk in 19 sometimes unit 7 (my archery tag allows me to hunt 5 units-7,8,9,19,191) and 2 or 3 years have got a late cow tag to fill the freezer (I have only shot 1 elk w/my bow and ironically shot 1 cow a few months later on the late hunt). Those are the only elk I have shot in unit 19. As far as quality for bucks and bulls in these units look somewhere else. There is a few but the are FAR and FEW between. CWD is in about 1% of the elk in these units. Deer CWD prevelence is about 5-20% The closer to Fort Collins the greater it will be. I would be more worried about finding and shooting a deer and elk than CWD! I have not hunted bucks in these units but my wife has shot 2 in 2 years (also her only years of hunting has been 2) one of which was a monster buck but this was done on private land close to town. i have shot a few does in unit 191. Yes you can hunt both deer and elk at the same time or 1 in 1 season and 1 in another if you want.
Hope it helps.
