You're looking at 2 different products. Mobile Connect places a call out to your mobile device when a caller dials your corporate desk phone. This consumes 2 PRI channels if the call came from outside your organization. Since the call is being bridged through your UCM cluster, advanced calling features can be used by entering certain digit strings.

Unified CM Service Parameters for Mobile Connect
The following items represent a partial list of Unified CM service parameters for the Cisco CallManager service that are related to Mobile Connect functionality:
•Enterprise Feature Access Code for Hold (Default value: *81)
This parameter indicates the feature access code used for the hold mid-call feature. This code is either manually keyed by the user or programmed as a key on a Smart Phone. This code is sent as a DTMF sequence from the remote destination phone back to the enterprise gateway and is relayed to Unified CM.
•Enterprise Feature Access Code for Exclusive Hold (Default value: *82)
This parameter indicates the feature access code used for the exclusive hold mid-call feature. When exclusive hold is invoked at the remote destination phone, the call cannot be picked up or resumed at the user's desk phone. This code is either manually keyed by the user or programmed as a key on a Smart Phone. This code is sent as a DTMF sequence from the remote destination phone back to the enterprise gateway and is relayed to Unified CM.
•Enterprise Feature Access Code for Resume (Default value: *83)
This parameter indicates the feature access code used for the resume mid-call feature. This code is either manually keyed by the user or programmed as a key on a Smart Phone. This code is sent as a DTMF sequence from the remote destination phone back to the enterprise gateway and is relayed to Unified CM.
•Enterprise Feature Access Code for Transfer (Default value: *84)
This parameter indicates the feature access code used for the transfer mid-call feature. This code is either manually keyed by the user or programmed as a key on a Smart Phone. This code is sent as a DTMF sequence from the remote destination phone back to the enterprise gateway and is relayed to Unified CM.
•Enterprise Feature Access Code for Conference (Default value: *85)
_______________________
These features can also be executed by using a Smart Client and pressing the appropriate hotkey button on your mobile device(Not sure if Cisco is referring to Mobility Advantage, haven't set that up yet.)
A button template can be configured on your desk phone for mobility; this will enable a "Send call to mobile phone" option (answer cell phone and the call is instantly transfered), and hanging up the mobile device will place the call on hold at your desk phone for a few seconds, giving you a second to pick it up.
I find it incredibly handy.
Regarding the second portion of your call, Unified Mobility Advantage is your friend. It consists of 2 servers (one acting as a proxy for the other) and allows a Cisco smart phone application to retrieve voice mails, browse the corporate directory, handle presence, etc.
You should really refer to Cisco's docs on these products for a comprehensive listing, though.
